Description

Recently, there has been a surge in interest for the wide bandgap (Eg ~ 4.9 eV) semiconductor gallium oxide (Ga2O3). A key driver for this boom is that single crystal wide area bulk β-Ga2O3 substrates have become commercially available [1] and a variety of methods have been shown to give high quality epitaxial growth [2,3]. Although Ga2O3 has a number of polymorph forms (α-, β-, γ-, δ- and ε) the more stable monoclinic phase (β-Ga2O3) has attracted the most attention. Amongst a whole range of potential applications power electronics, solar-blind photodetectors and UVC transparent electrodes offer exciting perspectives [3-5]. In this talk we give an overview of these applications illustrated with examples from the β-Ga2O3 development work carried out at the French oxide epiwafer start-up, Nanovation [4-7].
