Summary on Grant Application Form |
|
The proposed Ion Beam Imaging Spectrometer (IBIS) is an instrument that will develop the completely new technique of ion-beam induced transient spectroscopy imaging (referred to as 'ion-beam DLTS') for the quantitative mapping of deep-level defects in CVD diamond. The instrument will be used on the recently-funded nuclear microprobe and accelerator at the University of Surrey, which is being installed during 2001. The IBIS instrument will be the first ever development of a combined luminescence and ion-beam DLTS instrument, and the first application of ion-beam DLTS to diamond. The instrument will consist of a dedicated target chamber containing three complementary imaging techniques; ion-beam DLTS for the quantitative mapping and characterisation of deep level traps, Ion Beam Induced Luminescence (IBIL) for spectrally-resolved mapping of radiative centres, and Ion Beam Induced Charge (IBIC) for mapping of charge drift lengths, mobilities, and related electrical charge transport properties.A research program using IBIS will perform spatially resolved characterisation of traps and recombination centres in CVD diamond, and their correlation with the material's electrical properties, grain size and morphology. Specifically, the role of defects within graphitic crystallite boundary layers in limiting diamond sensor performance will be quantitatively investigated. Close feed-back with De Beers will aim to improve CVD diamond material quality and so extend the performance of a variety of CVD diamond sensors for ionising and UV radiation detection.
