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…

Growth of Be-doped GaInP/GaAs heterostructure bipolar transistor by all solid-source multiwafer production molecular beam epitaxy

A. Wilk, M. Zaknoune, S. Godey, S. Dhellemmes, P. Gérard, C. Chaix, F. Mollot

The rapid setup of the molecular beam epitaxy (MBE) growth process for GaInP/GaAs heterostructure bipolar transistor (HBT) in an all solid-source multiwafer production MBE system is reported. The first 100×100 μm2 large area test structures enable determination of the static gain, which is above…
