The Sula DLTS with Janis Optical Cryostat is a turn-key system for deep level transient spectroscopy which will allow unique electronic characterisation of materials. It has an optical window for photo-induced DLTS and a fast pulse interface. The combination of charge and current transient spectroscopy allows the system to function on both semiconductors and more insulating materials.
