Study of Highly Pixelated CdZnTe Detector for PET Applications
We are investigating the feasibility of a high-resolution PET insert device based on a Cadmium Zinc Telluride (CdZnTe) detector with 350 μm anode pixel pitch to be integrated into a conventional animal PET scanner to improve its [...]
Several types of GaN MOSFETs with normally-off operation have been fabricated on insulating substrate and evaluated. In recessed-gate GaN MOSFET, the threshold voltage (Vth) can be easily controlled, but the current drivability is modest and needs to be improved by adopting appropriate device structure [...]
Gas filled prototype of a CdZnTe pixel detector
CdZnTe pixel structures are currently the most promising detectors for the focal planes of hard X-ray telescopes, for astronomical observation in the range 5–100 keV. In Sharma et al. (Proc. SPIE 3765 (1999) 822) and Ramsey et al. [...]

We have demonstrated an efficient and compact passively Q-switched and mode-locked (QML) 1064 nm Nd:YVO4 laser by using a low temperature grown GaAs (LT-GaAs) saturable absorber as well as an output coupler. Stable QML with envelope duration as short as 10 ns and Q-switched repetition rate of 36 kHz was [...]
