We observed enhancement of thermionic emission (TE) and conversion (TC) characteristics by controlling spontaneous and piezo polarization and the band diagram of n-type AlGaN/GaN thermionic cathodes. The obtained TE current from N-polarity n-AlGaN fi

We present a high-density plasma source using a hollow cathode with an axial magnetic field. The hollow cathode consists of molybdenum plates coated by polycrystalline boron-doped diamond (PBDD) with a high yield of ion-induced secondary electrons. I

We observed the polarity-dependent thermionic emission and conversion characteristics of Si-doped n-type GaN-based cathodes with Cs adsorbed on their surfaces. Emission current from the surface of the GaN sample with N -polarity was markedly higher t

Realization of logic circuits from graphene is very attractive for high-speed nanoelectronics. However, the intrinsic ambipolar nature hinders the formation of graphene logic devices with the conventional complementary architecture. Using electrostat

Electron transport in bilayer graphene placed under a perpendicular electric field is revealed experimentally. Steep increase of the resistance is observed under high electric field; however, the resistance does not diverge even at low temperatures.
