Terahertz imaging using high electron mobility transistors as plasma wave detectors

S. Nadar, D. Coquillat, M. Sakowicz, H. Videlier, F. Teppe, N. Dyakonova, W. Knap, J.-M. Peiris, J. Lyonnet, D. Seliuta, I. Kasalynas, G. Valusis, K. Madjour, Didier Theron, Christophe Gaquière, M.-A. Poisson

Two experiments demonstrate that high electron mobility transistors (HEMTs) are well suited for terahertz (THz) imaging. We have shown that HEMTs can be effectively used as plasma wave detectors in a THz imaging system at frequencies higher than 1 THz at room temperature and this device are...

Kelvin probe force microscopy of charge transfer mechanisms from doped silicon nanocrystals

Lukasz Borowik, Koku Kusiaku, D. Deresmes, Didier Theron, Heinrich Diesinger, Thierry Melin, Thuat Nguyen-Tran, Pere Roca I Cabarrocas

The introduction of impurities in semiconductor nanocrystals is of fundamental interest to control their optical, electrical and magnetic properties[1]. Doping is essential to basically enhance electrical conductivity, and to build functional devices. This issue becomes of prime interest at the...

Tunable room temperature terahertz sources based on two dimensional plasma instability in GaN HEMTs

A. El Fatimy, T. Suemitsu, T. Otsuji, N. Dyakonova, W. Knap, Y. M. Meziani, S. Vandenbrouk, K. Madjour, Didier Theron, Christophe Gaquière, P. Prystawko, C. Skierbiszewski

In this work, we report on room temperature terahertz radiation from sub-micron size GaN/AlGaN based high electron mobility transistors (HEMTs). They could successfully replace the standard Fourier Transform spectrometer source and were investigated with a standard Si-bolometer as a detector. The...
