    Experimental demonstration of a two-dimensional hole gas in a GaN/AlGaN/GaN based heterostructure by optical spectroscopy by Méchin, Loïc, Médard, François, Leymarie, Joël, Bouchoule, Sophie, Duboz, Jean-Yves, Alloing, Blandine, Zuñiga-Pérez, Jesús, Disseix, Pierre

    Published 2024
    “…The objective of this article is to demonstrate, thanks to the combination of various optical spectroscopy techniques coupled to numerical simulations, the presence of a two-dimensional hole gas in a GaN/AlGaN/GaN heterostructure. This is made possible thanks to a GaN/AlGaN/GaN heterostructure displaying a micrometer-thick AlGaN layer and a GaN cap thicker than in conventional GaN-based HEMTs structures. …”
