Investigation of Surface States and Device Surface Charging in Nitride Materials Using Scanning Kelvin Probe Microscopy
In this work Scanning Kelvin Probe Microscopy (SKPM) was used to characterize surface states and device surface charging in nitride materials. Samples grown by Molecular Beam Epitaxy (MBE), Metal Organic Chemical Vapor Deposition (MOCVD) and Hydride Vapor Phase Epitaxy (HVPE) typically show a high …

Local Charging Behavior on GaN Surfaces
… studied by measuring the surface potential with scanning Kelvin probe microscopy (SKPM). The charging and discharging behavior of the surface appears to be strongly influenced by surface preparation and the presence of a surface oxide layer. If a substantial oxide layer exists, then both positive …

Formation of screen-printed contacts on multicrystalline silicon (mc-Si) solar cells
… of phosphorous occurs during Si-Ag interaction. Scanning Kelvin Probe Microscopy profiles have been studied to measure the surface potential of the metal semiconductor region. Current Voltage characteristics of the fired cells are presented. An improved technique to cross-section large lengths of …
