WebSep 22, 2014 · We report the drastic effect of film thickness on the structure and corresponding phonon behavior of crystalline GeTe ultrathin film. GeTe film with film thickness at ∼5 nm still shows good crystallization behavior and this highly scaled dimension confined almost all the crystallites to have preferred [111] orientation. The large specific …
WebAs can be inferred from the simple mathematical equations, high doping is responsible for a huge reduction in the current density and accordingly the PCE. A proposed solution is to reduce the GeTe layer thickness and add a Copper indium gallium selenide (CIGS) layer with a smaller thickness just above the GeTe thin film.
