Role of Gate Oxide in AlGaN/GaN High-Electron-Mobility Transistor pH Sensors
We report on a comparison of different gate oxides for AlGaN/GaN high-electron-mobility transistor (HEMT) pH sensors. The HEMTs show a linear increase in drain-source current as the pH of the electrolyte solut...

Fabrication approaches to ZnO nanowire devices
To date, most of the work on ZnO nanostructures has focused on the synthesis methods and there have been only a few reports of the electrical characteristics. We report on fabrication methods for obtaining dev...
