XHEMTs on Ultrawide Bandgap Single‐Crystal AlN Substrates
AlN/GaN/AlN XHEMTs [single‐crystal (“X‐tal”) high‐electron‐mobility transistors] are built on bulk AlN substrates with a 20 nm pseudomorphic GaN channel. This coherent epitaxial double heterostructure promises low‐defect, thermally efficient nitride electronics for next‐generation RF technology.

All‐Optical Logic Gates and Programmable Photonic Organo‐Polymer Devices
Four PDMS‐based photonic devices imitating the shapes of Y‐structure, hexagonal mesh, dual in‐phase quadrature, and cascaded MZI array are demonstrated and shown to function as all‐optical OR gates. Furthermore, a PDMS hexagonal mesh, containing dye‐doped regions, is shown to enable performance as a programmable photonic device, where its ...

VO2 Oscillator Circuits Optimized for Ultrafast, 100 MHz‐Range Operation
The present study demonstrates ultrasmall (≈30 nm) VO2 Mott memristor‐based oscillators which enter the >100 MHz frequency range via device scaling and optimization of the circuit layout for high frequency operation. Time‐resolved investigation of switching dynamics along with circuit‐level and physics‐based electrothermal simulations identify physical
