Thin Al1−xGaxAs0.56Sb0.44 diodes with extremely weak temperature dependence of avalanche breakdown [PDF]

Royal Society Open Science, 2017
When using avalanche photodiodes (APDs) in applications, temperature dependence of avalanche breakdown voltage is one of the performance parameters to be considered. Hence, novel materials developed for APDs require dedicated experimental studies.

Spiro‑Linked Double Tetraphenylethenes: Solid‐State Emission and Circularly Polarized Luminescence Imaging

Angewandte Chemie, EarlyView.
Two spirobisanthracene‐tetraphenylethene (SBA‐TPE) hybrid compounds are synthesized and their photophysical properties in the solid state reported. Circularly polarized luminescence in aggregates, films and dispersions is evaluated. Circularly polarized luminescence imaging is evaluated over crystals revealing discrimination of different types of ...

Superlattice avalanche photodiodes

Conference Proceedings. LEOS '97. 10th Annual Meeting IEEE Lasers and Electro-Optics Society 1997 Annual Meeting, 1997
Summary form only given. InGaAsP-InAlAs superlattice avalanche photodiode (SL-APD) is applied to the receiver of the analog video transmission as well as to the high-bit-rate digital transmission. The low noise, wide bandwidth, low distortion, and wide dynamic range characteristics of the SL-APD are fully exploited in the video transmission system. All
