Improved position sensitive detectors using high resistivity substrates

Abstract: Position sensitive detectors (PSDs) have the advantage of being single continuous devices with no dead zones unlike other types of optical sensors that must be arrayed to produce large area devices. An important aspect of using PSDs is the simplicity of implementing the devices in most applications, i.e. there is no requirement for additional electronics to read electronic output or for obtaining information over large areas. To this end it is advantageous for devices to produce large sensitivities and which c… Show more

“…The doping type of the top SiC layer has profound effects on the performance of the PSD. The resistivity of the diffusion layer is the main difference between n-SiC/p-Si and p-SiC/p-Si heterostructure that influences the position sensitivity . Electron mobility in SiC is approximately 1000 cm 2 V –1 s –1 at 300 K compared to a hole mobility of 125 cm 2 V –1 s –1 .…”

“…ЛФЭ возникает при неравномерном освещении pn-перехода в результате латеральной диффузии и рекомбинации фотогенерированных электроннодырочных пар [1][2][3][4]. Подобный эффект также исследовался в структурах металл−полупроводник (МП) [6][7][8][9][10][11] и металл−оксид−полупроводник (МОП) [12][13][14][15][16][17][18]. Этот эффект применяется в позиционно-чувствительных детекторах, поскольку при смещении светового пятна латеральное фотонапряжение меняется линейно [1,4,5].…”

“…Генерируемое фотонапряжение, как правило, измерялось на контактах, расположенных со стороны, противоположной освещению [2][3][4][5][6][7]. Однако недавно было показано [8,9,12,13], что чувствительность ЛФЭ в структурах МП и МОП может быть увеличена при освещении и расположении контактов со стороны пленки металла.…”
