ABSTRACT
In this letter we describe the operation of a new high-speed, high-gain amorphous silicon sensor. The device gain originates from the photoconductive properties of amorphous silicon but good light to dark sensitivity is obtained by suppressing the sensor dark current by means of a lightly p-type barrier layer. Optical gains in excess of 100 have been achieved with response times of approximately 200 μs.

    A tandem photoconductive switch, producing nearly rectangular electrical pulses with variable duration from 25 ps to 1 ns, was used for accurate turn-on delay measurements of a laser diode. Maximum electrical pulse amplitude was 75 V and both rise and fall times were 15 ps. The shortest delay...

    The electromagnetic endcap BGO calorimeter of the CMD-3 detector is ready for experiments at the new e+ e− collider VEPP-2000. Light readout is performed by silicon photodiodes. A thermalcontrol system that is able to maintain the calorimeter temperature at a level of 12 ±1°C was...

    By measuring the output signal of a SiC photodiode under short-pulse illumination with photon energies below the band gap, it was found that the response is determined by a second-order process, i.e., two-photon induced photoconductivity. This nonlinearity is suitable for realizing...

    Silicon photodiodes have been tested for resistance to vacuum-ultraviolet radiation at 121.6 nm. The responsivities of the p- n and n- p photodiodes under study were found to degrade by tens of percent at a VUV radiation dose on the order of tens of mJ/cm. The effect of reversible photocurrent...

    The dark alternating current (ac) parameters of commercially available silicon p-i-n-photodiodes are measured and compared at room temperature both in forward and reverse bias using the impedance spectroscopy technique. The ac behavior of the photodiodes is found to be almost the same. For bias...
