Multilayer gallium telluride (GaTe) films have been synthesized through atomic layer deposition (ALD) growth to enable large single domain thin films with negligible amount of grain boundaries. GaTe thin films are directly deposited onto double side polished c-cut sapphire substrates but can be transferred onto virtually any substrate choice. GaTe films measure 100s of nanometers in thickness and particularly ideal for thin film geometry measurements such as catalysis, photovoltaics, electronic transport, and others. GaTe films come with guaranteed PL, Raman, and semiconducting response.
