Transition from ballistic to ohmic transport in T-branch junctions at room temperature in GaInAs/AlInAs heterostructures

Jean-Sebastien Galloo, Emmanuelle Pichonat, Yannick Roelens, S. Bollaert, X. Wallart, A. Cappy, Javier Mateos, Tomás González, Hervé Boutry, Vincent Bayot, Lukasz Bednarz, Isabelle Huynen

We have developed technolow based on GaInAs/AIInAs for building ballistic devices working at room temperature. We present processes for ballistic devices (T-Branch Junctions (TBJs), YBranch Junctions (YBJs)). Then we present DC Characterization of TBJs to show the transition from ballistic to ohmic…

Raman characterization of Mg⁺ ion-implanted GaN

B. Boudart, Y. Guhel, J.C. Pesant, P. Dhamelincourt, M.A. Poisson

Mg+ ions were implanted at room temperature in n-type hexagonal GaN for the device isolation purposes. The implantation dose varied from 7.5 × 1012 to 1016 ions cm-2. We performed resonance Raman spectroscopy and DC electrical measurements in order to monitor the structural and electrical changes…

Theoretical analysis of a directional source for four-dimensional seismic monitoring

Madjid Berraki, Bertrand Dubus, Axelle Baroni

The aim of four dimensional seismic monitoring is to monitor the changes in the subsurface in time; to achieve this, measurements are continuously repeated with the same space configuration. Reliability and repeatability of the acquisition footprint are thus key requirements for four dimensional…
