Over the last decade, field-effect transistors (FETs) with nanoscale dimensions have emerged as possible label-free biological and chemical sensors capable of highly sensitive detection of various entities and processes. While significant progress has been made towards improving their sensitivity, much is yet to be explored in the study of various critical parameters, such as the choice of a se...

As the scaling of MOSFETs continues the requirement to maintain electrostatic integrity dictates an aggressive reduction of the oxide thickness below 1 nm, introducing intolerably high gate leakage [1]. This has led to the introduction of high-κ materials in the gate stack offering the required SiO2 equivalent oxide thickness at increased physical thickness and reduced gate leakage. There are m...

We experimentally observe the “superprism effect” in a periodic thin-film structure acting as a one-dimensional photonic crystal. The design of non-periodic structures exhibiting a linear shift with wavelength in the EDFA C-band is discussed. 2002 Optical Society of America OCIS codes: (260.2030) Dispersion; (060.4230) Multiplexing; (230.4170) Multilayers WDM systems create a strong need for c...

A nanoscale device consisting of a metal nanowire, a dielectric, and a gate is proposed. A combination of quantum and thermal stochastic effects enable the device to have multiple functionalities, serving alternately as a transistor, a variable resistor, or a simple resistive element with I −V characteristics that can switch between ohmic and non-ohmic. By manipulating the gate voltage, stochas...

Guided-mode resonance filters (GMRFs) are highly compact structures that can produce a strong frequency response from a single thin layer of dielectric. When a GMRF is formed onto a curved surface, the local angle of incidence varies over the aperture of the device and the overall performance significantly degrades. In the present work, we spatially varied the grating period of a curved GMRF to...

The present paper describes the recent developments in the device engineering for microelectronics and nanoelectronics. The perspectives for the future show a narrow margin in silicon technology. Hence Engineering in Devices and materials becomes a must. The investigation carried out illustrates the various materials technology that can lengthen the silicon technology lifetime and eventually br...

We report the integration of two technologies: droplet microfluidics using electrowetting-on-dielectric (EWOD) and individual particle manipulation using optoelectronic tweezers (OET)-in one microfluidic device. The integrated device successfully demonstrates a sequence involving both EWOD and OET operations. We encountered various challenges during integration of the two different technologies...
