Point Contact Germanium detectors (PCGe) technique is ideal for the search of exiotic particle the high energy physics due to its excellent resolution and the large fiducial mass .The p-type Ge detectors have anomalous surface behaviour which needs to be characterized and understood. We describe the methods and results of a research program whose goals are to identify the bulk and surface events via software pulse shape analysis techniques, and to devise calibration schemes to evaluate the selection efficiency factors. We report the status of developments in Electro-Cooled Ge Detectors to achieve low detector threshold and background in sub keV region.
