Abstract: A novel design for a nitrogen polar high-electron-mobility transistor (HEMT) structure comprising a GaN/InGaN composite channel. As A novel design for a nitrogen polar high-electron-mobility transistor (HEMT) structure comprising a GaN/InGaN composite channel. As illustrated herein, a thin InGaN layer introduced in the channel increases the carrier density, reduces the electric field in the channel, and increases the carrier mobility. The dependence of p on InGaN thickness (tInGaN) and indium composition (xIn) was investigated for different channel thicknesses. With optimized tInGaN and xIn, significant improvements in electron mobility were observed. For a 6 nm channel HEMT, the electron mobility increased from 606 to 1141 cm2/(V·s) when the 6 nm thick pure GaN channel was replaced by the 4 nm GaN/2 nm In0.1Ga0.9N composite channel.

Abstract: A first device specifies a privacy specification. The privacy specification includes at least a safe zone and a precision parameter may also be specified. A second device, such as an untrusted server, uses the privacy specification to provide guidance to the first device on how to perturb sensitive data. The first device then uses the guidance to transform sensitive data and provides it to the second device. The data transformation permits the first device to share sensitive data in a manner that preserves the privacy of the first user but permits statistics on aggregated data to be generated by an untrusted server.
