Abstract
Progress with Schottky diode and p i n diode GaAs detectors for minimum ionizing particles is reported here. The radiation hardness and potential speed of simple diodes is shown to be more than competitive with silicon detectors. A discussion is given of the present understanding of the charge transport mechanism in the detectors as it influences their charge collection efficiency. Early results from micro-strip detectors are also described, (which are relevant for high radiation regions of LHC detectors near the beam pipe and in the forward region).
