Double Gate 6H-Silicon Carbide Schottky Barrier FET as Dielectrically Modulated Label Free Biosensor

Ambipolar Effect Free Double Gate PN Diode Based Tunnel FET

Converter Using Silicon Carbide Schottky Diode

Silicon carbide (SiC) is the perfect cross between silicon and diamond. The crystal lattice of SiC is identical to silicon and diamond, but, exactly half the lattice sites are occupied by silicon atoms and half by carbon atoms. Like-diamond siC has electronic properties superior to silicon, but, unlike diamond it is also manufacturable. The thermal leakage current (dark current) in SiC is sixte...

Label-free silicon photonic biosensor system with integrated detector array.

An integrated, inexpensive, label-free photonic waveguide biosensor system with multi-analyte capability has been implemented on a silicon photonics integrated circuit from a commercial CMOS line and tested with nanofilms. The local evanescent array coupled (LEAC) biosensor is based on a new physical phenomenon that is fundamentally different from the mechanisms of other evanescent field sensor...

Schottky barrier inhomogeneities at the interface of few layer epitaxial graphene and silicon carbide

In this work, we study electron transport across the heterojunction interface of epitaxial few-layer graphene grown on silicon carbide and the underlying substrate. The observed Schottky barrier is characterized using current-voltage, capacitance-voltage and photocurrent spectroscopy techniques. It is found that the graphene/SiC heterojunction cannot be characterized by a single unique barrier ...

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...
