Single-crystal diamond Schottky photodiodes have been developed following a WC-diamond-TiC/Ti/Ag vertical structure for X-ray dosimetry with characteristics of low leakage current and the capability of zero-bias operations. Continuous and modulated X-ray measurements show that the devices developed provide a linear response to dose rate at low bias voltages (< 2.5 V) and at modulation frequencies > 130 Hz.

Abstract
Single-crystal diamond Schottky photodiodes have been developed following a WC-diamond-TiC/Ti/Ag vertical structure for X-ray dosimetry with characteristics of low leakage current and the capability of zero-bias operations. Continuous and modulated X-ray measurements show that the devices developed provide a linear response to dose rate at low bias voltages (< 2.5 V) and at modulation frequencies > 130 Hz. This supports their application in modulated radiotherapy treatments. © 1980-2012 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
