MD-PICTS

MD-PICTS is a modification of MDP, where temperature dependent measurements of the defect part of the transient are accomplished.

MD-PICTS – microwave detected photo induced current transient spectroscopy

MD-PICTS is a modification of MDP, where temperature dependent measurements of the defect part of the transient are accomplished. This allows for a spatially resolved defect characterization. Similar to DLTS (deep level transient spectroscopy), the activation energy and the capture cross section of the defects can be determined. However, in contrast to DLTS, no contacts are needed. This is extremly valuable for defect identification and material quality improvement.
