Ultrahigh frequency DC-to-DC converters using GaAs power switches

Sami Ajram, Georges Salmer

A detailed investigation of the switching characteristics for high frequency power devices based on different technologies has been provided: BJT, MOSFET, and MESFET/HEMT structures are considered. Advantages of GaAs power switches over silicon ones have been established and illustrated. Hybrid…

AlGaN/GaN based MOSHFETs with Different Gate Dielectrics and Treatments

D. Mistele, Zahia Bougrioua, T. Rotter, I. Moerman, K.S. Röver, M. Seyboth, V. Schwegler, J. Stemmer, F. Fedler, H. Klausing, O.K. Semchinova, J. Aderhold, J. Graul

AlGaN/GaN based hetero field effect transistors (HFETs) were capped with different dielectrics, characterized, and tested for DC performance. As dielectrics we use SiO2 and photoelectrochemical (PEC) grown AlxGa2-xO3. Combination of this two dielectrics show best performance with respect to gate…

Wave shaping through finite electromagnetic band-gap structure

Olivier Vanbésien, Tahsin Akalin, Jorge Carbonell, Jérôme Danglot, Didier Lippens

Transmission mechanisms and wave steering under localized feeding conditions through a finite electromagnetic bandgap structure are investigated both experimentally and theoretically. The artificial propagating medium consists of a two-dimensional metallic wire structure dimensioned for millimetre…

Tight binding for complex semiconductor systems

Christophe Delerue, Michel Lannoo, Guy Allan

In this review, we illustrate multiple aspects of the application of the empirical tight binding (ETB) approximation. We begin by summarizing the general principles of ETB where the Hamiltonian matrix is written in a restricted atomic basis set and in terms of a relatively limited number of…
