External Quantum Yield

The external quantum yield of silicon avalanche photodiode in the wavelength range of 120-170 nm was performed. It was shown that the engineered avalanche photodiode has the external quantum yield of 24-150 electron/proton under reverse bias voltage of 230-345 V, respectively. The testing of worked out avalanche photodiode by means of pulse flash of 280 and 340 nm wavelength demonstrates the speed, corresponding to the bandwidth not less than 25 MHz.

Abstract Diamond solid-state devices are very attractive to electrically control the charge state of Nitrogen-Vacancy (NV) centers. In this work, Vertical p-type Diamond Schottky Diode (VDSDs) is introduced as a platform to electrically control the interconversion between the neutral charge NV (NV0) and negatively charged NV (NV-) centers. The photoluminescence (PL) of NV centers generated by ion-implantation in VDSDs shows the increase of NV- Zero Phonon Line (ZPL) and phonon sideband (PBS) intensities with the reverse voltage, whereas the NV0 ZPL intensity decreases. Thus, NV centers embedded into VDSDs are converted into NV- under reverse bias voltage. Moreover, the optically detected magnetic resonance (ODMR) of NV- exhibits an increase in the ODMR contrast with the reverse bias voltage and splitting of the resonance dips. Since no magnetic is applied, such a dip splitting in ODMR spectrum is ascribed the Stark effect induced by the interaction of NV- with the electric field existing within the depletion region of VDSDs.

Amorphous silicon imaging arrays with ∼3×105 pixels have recently been developed and x-ray images of low contrast anatomical phantoms have been demonstrated. This paper reports on the linearity of response of these a-Si:H imaging pixels as a function of reverse bias voltage. The fraction of the imaging pixel's full signal range that maintains a linear response has been found to increase with increasing voltage.
