Adaptive IIR and Nonlinear Filters

New porphyrin-based charge storage materials will be synthesized, including porphyrin monomers, dyads, and triple-decker sandwich coordination compounds. Novel approaches for development of charge-transfer layers also will be investigated. Molecular-based charge-storage materials will be incorporated into a variety of novel nanodevice designs in the Misra lab. Material samples will be delivered from the Lindsey lab to collaborators (David Bocian, UC Riverside; Veena Misra, NCSU ECE) on a regular basis for physical studies. The collaborative effort of the three groups will lead to new insights in molecular information storage. The Misra and Lindsey labs will split the funds allocated to our labs. Porphyrin-Based Molecular Memories Jonathan S. Lindsey, Veena Misra University of California Riverside $300,000 09/19/06 09/30/07 This activity focuses on novel approaches for the development of molecular memories. Redox active molecules will be incorporated into a variety of novel nanodevices with a particular emphasis on achieving solid-state designs. Research in this area will include substrate engineering and control of tunnel barrier design aimed at increasing the speeds for addressing the molecular information storage medium. In situ construction of molecular architectures provides a mechanism for increasing the charge densities on the surface of the semiconductor materials. Atomic layer deposition approaches will be explored for assembling solid-state electrolyte equivalent materials on the molecular storage medium on various substrates. Scalable Strained Silicon MOSFET Technology with Advanced Gatestack Materials Veena Misra, Mehmet C. Ozturk National Science Foundation $270,000 07/01/03 06/30/07 The goal of this project is to evaluate alternative high-K dielectrics and metal electrodes on strained silicon devices. The impact of varying strain levels in the silicon will be evaluated on the interfacial properties, mobility and reliability of the gatestacks. Carolina Center of Cancer Nanotechnology Excellence John F. Muth UNC UNC Chapel Hill $101,586 09/30/05 08/31/06 The purpose of this project is to fabricate nano-lights that may be able to illuminate cells as a novel form of microscopy and help in the understanding of how cancerous cells are different form health cells. It is a multidisciplinary project with biologists at the University of North Carolina at Chapel Hill. Carolina Center of Cancer Nanotechnology Excellence John F. Muth UNC UNC Chapel Hill $103,868 09/30/06 08/31/07 At present, single cell and single molecule fluorescence studies have been a powerful toolset for understanding cellular processes. However, in traditional optical microscopy most of the photons are wasted with only a very small number of photons are exciting fluorophores of interest. The remaining photons are producing autofluorescence from the medium and heat within the cell. The goal of this portion of the project is to fabricate an array of nano-lights to create an intelligent microscope slide. By breaking the paradigm of requiring an external light source the nano-light emitters will be a powerful new tool for investigating cell/surface interactions.

NC State University College of Engineering Research Projects Electrical and Computer Engineering Investigation of the Fundamental Properties of Amorphous and Crystalline Oxide Semiconductors. John F. Muth Army Research Office $99,999 03/21/06 05/31/07 The purpose of this project is to investigate a new class of novel semiconducting oxide materials. Some Interesting properties of these materials is that that they have a electron mobility that is an order of magnitude faster than amorphous silicon, and they are transparent to visible light. This opens up the possibility of transparent electronics for displays and other applications. Micromachined Chemical Sensor John F. Muth Naval Research Laboratory $444,998 08/15/05 08/15/08 The need to be able to detect chemical or explosive agents has grown greatly in importance in recent years. Present sensor systems require the sensor and readout to be at the location of the agent. The ability to remotely interrogate sensors from a distance would be advantageous. This proposal involves the fabrication of micromachined sensors that will be sensitive to chemicals and can be read out by a laser from a distance. Photonic Devices for Underwater Communications John F. Muth US Navy $543,812 05/01/03 12/31/06 Radio waves do not penetrate ocean water, and acoustic signals have relatively low bandwidth for communicating large amounts of data. Blue and Green light emitting diodes and lasers provide one possible means of forming short range high bandwidth communication systems that will work in ocean water. This project investigates novel optical devices that will enable underwater optical communication systems for unmanned underwater vehicles and underwater networks. National Nanotechnology Infrastructure Network Triangle National Lithography Center Carlton M. Osburn Cornell University Unfunded 03/01/04 02/28/09 The Triangle National Lithography Center (TNLC), is a joint venture of NC State and UNC-Chapel Hill, whose centerpiece is a state-of-the-art, 193 nm optical lithography scanner for rapid turnaround time and high volume patterning. Automated wafer tracks are used for resist processing. The tool can “print” 80 nm isolated features, and resist trimming can be used to produce even smaller features. The scanner is housed in Class 100 facilities within the NCSU Nanofabrication Facility (NNF) which provides: reactive ion etching, film deposition, thermal processing, diffusion, chemical mechanical polishing, cleaning, and characterization tools. The TNLC is an affiliate of the National Nanotechnology Infrastructure Network (NNIN) and, along with the NNF, is open to all researchers. A Novel Laboratory Based Introduction to Electrical and Computer Engineering for Sophomores Mehmet C. Ozturk National Science Foundation $304,643 02/01/02 08/31/06 The goal of this program is to develop a novel, introductory course for electrical and computer engineering sophomores. The course is centered around a hardware laboratory with traditional bench-top measurement equipment and new laboratory hardware specifically designed and constructed for the new experiments. The course begins with fundamental concepts and moves onto different specialization areas supported by motivating experiments based on real-life applications. The new laboratory hardware allows the students to work on these applications at an introductory level. Another component of this program is the Virtual Laboratory in the form of Java applets. Recessed SiGe and SiC Source/Drain Engineering For Future CMOS Technologies Employing Uniaxial Channel Stress For Channel Mobility Enhancement Mehmet C. Ozturk, Veena Misra Semiconductor Research Corp. $128,000 07/01/06 06/30/07 In this work, we explore methods to form low-resistivity source/drain junctions and contacts for CMOS technology nodes down to 22 nm. The work is performed in two parallel tracks. In the first track, we explore selective epitaxy of SiC alloys in recessed source/drain regions with the objective of inducing tensile stress for electron mobility enhancement. In the second track, we explore novel contact formation schemes to both p+ SiGe and n+ SiC source/drain junctions in order to reduce the contact resistivity of these contacts down to 10-9 ohm-cm2 to limit the series resistance to a small fraction of the channel resistance.
