Effect of tensile stress on the various components of the off current of n-channel metal-oxide-semiconductor transistors
The authors found that tensile stress actually slightly increases the on current and the subthreshold off current but it slightly decreases the gate leakage current and the drain junction leakage curr...

Avalanche p-i-n photodiodes of various mesa areas were fabricated on AlN templates for back illumination for enhanced performance through hole-initiated multiplication, and the effects of increased area on device performance were studied. Avalanche multiplication was observed in mesa sizes up to 14 063 µm2 under linear mode operation. Uniform gain and a linear increase of the dark current with area were demonstrated.
