In-plane polarities of nonpolar wurtzite epitaxial films deposited on m- and r-plane sapphire substrates

Philippe Vennéguès, Tiankai Zhu, Z. Bougrioua, Denis Martin, J. Zuniga-Perez, Nicolas Grandjean

The in-plane polarities of GaN and ZnO non-polar films deposited on r - and m-sapphire are compared. The polarity is unique on r-sapphire and mixed on m-sapphire because the direction on the substrate surface parallel to the wurztite c-direction is polar in the first case and nonpolar in the second…

A High Mobility Field-Effect Transistor as an Antenna for sub-THz Radiation

Maciej Sakowicz, Jerzy Łusakowski, Krzysztof Karpierz, Marian Grynberg, Wojciech Gwarek, Stephane Boubanga Tombet, Dominique Coquillat, Wojciech Knap, Andrey Shchepetov, S. Bollaert

The experiments on radiation coupling to field effect transistors working as terahertz radiation detectors are reported. Two types of high electron mobility transistors: InGaAs/InAlAs and GaAs/AlGaAs, with different layout geometries are studied. We show that terahertz radiation coupling efficiency…
