Power limiting and self-switching which is caused by the field shielding effects of charge created by photoconductivity at 1.06 μm in CdTe have been demonstrated. The effect has a relatively low threshold of ∼100 μW/cm2, an extrapolated switching time of microseconds, and can be used over the wavelength band of approximately 0.9–1.3 μm.

    In this work, we compare the photodetector performance of single nearly defect-free undoped and n-i-n GaN nanowires (NWs). Undoped NWs present a dark current three orders of magnitude lower than n-i-n structures, about ten times lower gain, and a strong dependence of the measurement environment....

The dynamical operator of the Markov model can then be subtracted from...
