High speed InAs electron avalanche photodiodes overcome the conventional gain-bandwidth product limit [PDF]
, 2011 High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of conventional APDs, is shown not to

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations
Advanced Functional Materials, EarlyView.β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Microwave PIN diodes for GaAs IC
Electronics Letters, 1985 The letter describes the design and fabrication techniques for successful realisation of two types of GaAs PIN diodes which lend themselves to integration into GaAs ICs. PIN diodes with a new shallow trench structure exhibit superior microwave performance to the interdigitated structure.
