Ambipolar Effect Free Double Gate PN Diode Based Tunnel FET

Double-Gate Tunnel FET With High-κ Gate Dielectric

In this paper, we propose and validate a novel design for a double-gate tunnel fi eld-effect transistor (DG Tunnel FET), for which the simulations show significant improvements compared with single-gate devices using an SiO2 gate dielectric. For the fi rst time, DG Tunnel FET devices, which are using a high-κ gate dielectric, are explored using realistic design parameters, showing an ON-current...

Step-gate polysilicon nanowires field effect transistor compatible with CMOS technology for label-free DNA biosensor.

Currently, detection of DNA hybridization using fluorescence-based detection technique requires expensive optical systems and complex bioinformatics tools. Hence, the development of new low cost devices that enable direct and highly sensitive detection stimulates a lot of research efforts. Particularly, devices based on silicon nanowires are emerging as ultrasensitive electrical sensors for the...

Biosensor Array for Label-Free Biomolecular Detection

Biosensors are one of the fundamental detection platforms in biotechnology. They take advantage of unique biomolecular interactions to capture and detect specific analytes on a surface. The detection versatility of biosensors has always been their key advantage and it has been demonstrated that they can detect almost any analyte such as DNA, proteins, metabolites, and even micro-organisms. Howe...

Label-Free Biosensor Imaging on Photonic Crystal Surfaces

We review the development and application of nanostructured photonic crystal surfaces and a hyperspectral reflectance imaging detection instrument which, when used together, represent a new form of optical microscopy that enables label-free, quantitative, and kinetic monitoring of biomaterial interaction with substrate surfaces. Photonic Crystal Enhanced Microscopy (PCEM) has been used to detec...
