With a dense two-dimensional hole gas (2DHG) p-type conductive layer near the surface, hydrogen- terminated (C-H) diamond metal-oxide-semiconductor field-effect transistors (MOSFETs) have shown typical normally-on operations and high breakdown voltages ( {V}_{\text {BR}} ). Owing to the high MOS interface quality, the oxidized silicon-terminated (C-Si–O) diamond MOSFETs have featured excellent n...Show More
The growth of gradual boron-doped diamond epitaxial layer was achieved by microwave plasma chemical vapor deposition (MPCVD). Secondary ion mass spectrometry (SIMS) results show that the effective doping concentration range is from 1015 cm−3 to 1019 cm−3, and the doping layer thickness is about 45 nm. Boron-doped diamond Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) was prepared by us...Show More
Hydrogenated silicon-doped (Si-doped) diamond was prepared by magnetron sputtering silicon on IIa CVD diamond surface and following Si etch/diffuse process at 1000 °C in a hydrogen atmosphere in MPCVD. The silicon doping concentration was higher than $1\times 10^{{18}}$ cm−3 among the depth of 25 nm. The hydrogenated Si-doped diamond surface demonstrated the simultaneous presence of C–H and C–Si...Show More
We report on achieving high conductivity hydrogenated boron (B) and silicon (Si) co-doped diamond with a room-temperature Hall result of a square resistance of 2724 ohm/sq, a sheet hole density of ${3}.{3}\times {10} ^{{13}}$ cm−2, and a hole mobility of 68.9 cm2/Vs. The co-doping of B and Si is realized in such a way. First, etch solid BN disk by hydrogen plasma in microwave plasma chemical vap...Show More
Interactive control is very important for unmanned swarm systems to understand human intentions and execute tasks. However, traditional interactive control usually uses a keyboard, mouse, or remote controller, which is not intuitive and convenient enough. This paper proposes a natural interaction control method based on gesture recognition for unmanned swarm systems. First, considering the real-ti...Show More
