Proposal for a network to develop x-ray and charged particles detectors in gaas

Obiettivo



Members of the Institute of Semiconductor physics, Vilnius, have already collaborated with some members of the Network, supported by the World Laboratory. Their expertise in GaAs electronic circuits and in the study of electrical noise in semiconductor devices would be an extremely valuable addition to the Network, in the areas of read-out circuitry for pixel detectors and of understanding the limitations on performance:set by noise.
Electronic engineers from Vilnius already have a prototype
preamplifier for Gaas microstrip detectors. Their contribution to the Network would be a read-out system optimised for the pixel detectors. The physicists of the Institute would undertake a study of the noise frequency dependence in both the pixel detectors and in the read-out electronics, with the aim of achieving the optimum signal:noise ratio through a better understanding of charge trapping in the Gaas materials. The collaboration between Lancaster and Prague in the investigation of Gaas wafer characteristics will complement the noise studies described above, in helping to identify the nature and concentration of trapping centres using their particular expertise in DLTS and photoluminescence techniques. This will indicate the most appropriate wafer material and annealing treatment for our application.
The proposer from Prague has been involved in a peripheral way with the solid-state aspects of the networks development of Gaas detectors. In particular he has made conventional PICTS measurements on existing devices and advised on trap properties.
This collaboration will be intensified over the proposed 12 months with an eight month visit to Lancaster University. His particular expertise will be to take measurements and interpret these in terms of device models during the four remaining months in Prague.
The Vilnius and Prague groups would both make an invaluable
contribution in expertise and manpower to the Network. In the event of restricted funds forcing us to make an invidious choice between the two possible contributions, our priority would have to lie with the Vilnius application and the unique addition which they could offer to our project. (NB - duration of Prague component is 12 months only)
