ZnO nanorods are promising materials for many applications, in particular UV detectors. In the present paper, properties of high crystal quality individual and nanorod arrays grown by self-catalytic CVD method have been investigated to assess their possible applicationsfor photodetectors. X-ray diffraction, Raman spectroscopy cathodoluminescence investigations demonstrate nanorods. The resistiv...

AlGaN alloys are promising for field emission devices due to their low electron affinities. However, there have been limited demonstrations of vacuum transistors so far. This letter combines a new self-aligned-gate (SAG) process and digital-etching tip sharpening demonstrate three-terminal SAG emitter arrays (FEAs). These show turn-on voltage 19.5 V an anode current density (J <sub xmlns:mml="h...
