E-mail address: [email protected] A novel device design for enhancement mode operation of III-nitride high electron mobility transistor (HEMT) structure has been proposed and demonstrated. The proposed HEMT device structure consists of a multi-heterojunction (SiO2/AlxGa1 xN/GaN/A...

Enhancement Mode Antimonide Quantum Well MOSFETs with High Electron Mobility and GHz Small-Signal Switching Performance

This paper demonstrates, for the first time, enhancement mode antimonide MOSFETs by integrating a composite highgate stack (3nm Al2O3-1nm GaSb) with ultrathin InAs0.7Sb0.3 QW (7.5nm). The MOSFET exhibits record high electron drift mobility of 5200 cm2/Vs at a carrier density (Ns) of 1.8x1012cm-2, sub-threshold slope of 150mV/decade, ION-IOFF ratio of ~4000x within a voltage window of ~1V, high ...

Surface morphology of Al0.3Ga0.7N/Al2O3-high electron mobility transistor structure.

We present surface properties of buffer films (AIN and GaN) and Al0.3Gao.zN/Al2O3-High Electron Mobility Transistor (HEMT) structures with/without AIN interlayer grown on High Temperature (HT)-AIN buffer/Al2O3 substrate and Al2O3 substrate. We have found that the GaN surface morphology is step-flow in character and the density of dislocations was about 10(8)-10(9) cm(-2). The AFM measurements a...
