In situ epitaxial surface passivation of GaAlN/GaN HEMT heterostructures grown by LP-MOCVD

Marie-Antoinette Di Forte-Poisson, Nicolas Sarazin, M. Magis, Maurice Tordjman, Erwan Morvan, Raphaël Aubry, J. Di Persio, Bertrand Grimbert

This paper reports on in situ passivation studies of GaAlN/GaN High electron mobility transistors (HEMT) structures grown by low-pressure metalorganic vapour phase epitaxy (LP-MOVPE) on sapphire and silicon carbide substrates. GaN, GaAlN, AlN and AlN/GaN superlattice (SL) layers have been deposited...

Selective filtering of confined optical waves in a straight waveguide coupled to a lateral stub

Yan Pennec, Maxime Beaugeois, Bahram Djafari-Rouhani, Abdellatif Akjouj, Jerome O. Vasseur, L. Dobrzynski, Jean-Pierre Vilcot, Mohamed Bouazaoui, J.P. Vigneron

We report numerical simulations, based on a finite difference time domain (FDTD) method, of light propagation in two-dimensional semiconductor micro optical waveguides coupled to one or several lateral stubs. The incident wave which is of transverse magnetic polarization (TM) is either...

Quick planarisation based on hydrogen silsesquioxane (HSQ) for deep etched InP based structures

Malek Zegaoui, Joseph Harari, Nargess Choueib, V. Magnin, Didier Decoster

The ability of HSQ resist films to planarise active deep etched (1.5-2m) InP based structures with electrodes is demonstrated for the first time. Vertically etched III-V semiconductor devices require planarisation of the passivation material for metal interconnections and device integration. A new...

Composition and size-dependent extinction coefficient of colloidal PbSe quantum dots

Iwan Moreels, Karel Lambert, David de Muynck, Frank Vanhaecke, Dirk Poelman, José C Martins, Guy Allan, Zeger Hens

Inductively coupled plasma mass spectrometry (ICP-MS) was combined with UV–vis−NIR spectrophotometry and transmission electron microscopy to determine the nanocrystal composition and molar extinction coefficient ϵ of colloidal PbSe quantum dot (Q-PbSe) suspensions. The ICP-MS results show a...

Uncovering forbidden optical transitions in PbSe nanocrystals

Jeffrey J. Peterson, Huang Libai, Christophe Delerue, Guy Allan, Todd D. Krauss

The 1Sh,e−1Pe,h exciton transition energy of PbSe nanocrystals was determined via two-photon photoluminescence excitation spectroscopy and was found to be in good agreement with predictions from a tight-binding calculation. The two-photon excitation peak occurs at energies very close to a strong...
