This report describes the improvements in understanding of transport phenomena in cadmium zinc telluride radiation sensors achieved through studies of alpha particle response and spatially resolved photoconductivity mapping. Alpha particle response waveforms and photocurrent profiles both indicate non-uniformities in the electric field which may have detrimental effects on detector performance. Identifying and eliminating the sources of these nonuniformities will ultimately lead to improved detector performance
