Abstract: The present disclosure describes porous GaN layers and/or compliant substrates used to enable relaxation of previously strained top layers and the deposition of relaxed or partially relaxed on top. Relaxed In GaN layers are fabricated without generation of crystal defects, which can serve as base layers for high performance long wavelength light emitting devices (LEDs, lasers) solar cells, or strain engineered transistors. Similarly, relaxed AlGaN layers can serve as base layers for high performance short wavelength UV light emitting devices (LEDs, lasers) solar cells, or wide bandgap transistors.

Abstract: A method for secure debugging in a multitenant cloud environment where an application server maintains a host application shared by multiple tenant users can be implemented. The method can receive a request from a tenant user to debug the host application associated with a tenant user, and responsive to the request, deploy an application runtime environment comprising an application container encapsulating the host application associated with the tenant user and a debugger container encapsulating a debugging software running on the application server. The method can set at least a breakpoint in source code of the host application through a user interface of the debugging software, run the host application associated with the tenant user in the application runtime environment, and evaluate an expression entered through the user interface of the debugging software after the host application associated with the tenant user hits the breakpoint.

Abstract: A method for fabricating a device, as well as the device itself, which includes growing a bonding layer on a first wafer or substrate, wherein the bonding layer includes at least partially relaxed features; and then bonding a second wafer or substrate to the features in on the first wafer or substrate, to cap and contact the features with separately grown material.

Abstract: Derivative cancellation techniques have been used to linearize transistors using multiple discreet devices. However at frequencies approaching and in the mm-wave regime the use of individual devices no longer works due to the parasitics associated with combining the devices. In this invention device structures are described which apply the derivative cancellation technique in a single device thus removing the detrimental impact of combining. In one example, an N-polar transistor structure includes a channel; a cap structure comprising a plurality of cap layers on or above the channel; a source contact and a drain contact to the channel; and a castellated, stepped, or varying pattern formed in the cap layers so that gate metal deposited on the pattern forms at least two different threshold voltages and current combines in the ohmic region with essentially zero parasitic inductance.

Strain is introduced using buffer layers or source and drain regions of different composition.

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.
