In this work we analyse the performance of Pt- and Ni-based Schottky metallizations on AlxGa1−xN (x = 0, 0.31). An intermediate thin Ti layer is shown to enhance the thermal stability of Pt/Au, and leads to an increase of the Schottky barrier height. Pt/Ti/Au contacts on GaN provide a barrier...

Statics and dynamics in giant magnetostrictive Tbx/Fe(1-x)/-Fe0.6Co0.4 multilayers for MEMS

Jamal Ben Youssef, Nicolas Tiercelin, Fabienne Petit, Henri Le Gall, Vladimir Preobrazhensky, Philippe Pernod

In the present paper, giant magnetostric-tive thin films have been investigated for future micro-electromechanical systems (MEMS) purposes. For this goal, flexural and torsional motions have been studied in low field anisotropic giant magnetostrictive (GMS) single domain state (SDS) exchange-...

Monolithic integrated circuits incorporating InP-based heterostructure barrier varactors

T. David, S. Arscott, J.-M. Munier, Tahsin Akalin, Patrick Mounaix, Gérard Beaudin, Didier Lippens

Fully integrated monolithic circuits incorporating InP-based heterostructure barrier varactor (HBV) frequency multipliers have been fabricated via epitaxial liftoff and transfer-substrate techniques onto a quartz substrate. We have obtained a maximum output power of 6 mW at 288 GHz: corresponding...

Electromagnetic generation between 0.1 and 3 terahertz has been demonstrated using ultrafast photodetectors loaded by broadband antennas and pumped by 0.8 µm stable lasers. Ultrashort response times have been achieved by means of low-temperature-grown (LTG) GaAs in a deep submicron interdigited...
