1. 1. Nanowire devices for X-ray detection

   Författare :Lert Chayanun; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanowires; Nanowire solar cells; X-ray detectors; X-ray beam induced current;

   Sammanfattning : High spatial resolution X-ray microscopy has become a dedicated tool to study nanocrystals and nanostructure devices in recent years. In general, the spatial resolution of X-ray microscopy depends on the spot size of the X-ray beam and the pixel size of X-ray detectors. LÄS MER
