Active tuning of the optical response of field-effect-gated transparent conductive oxides

چکیده
Transparent Conductive Oxides (TCOs) are a class of materials with high optical transparency and electrical conductivity. This combination makes them extremely appealing for solar cells, optoelectronics infrared-plasmonics applications. In this work, we report the active tuning response aluminium-doped ZnO (AZO) films upon gating within parallel-plate capacitor configuration. We investigated electrical-bias-dependent thin AZO fabricated by pulsed laser deposition means spectroscopic ellipsometry (SE). Calculations based on an exponentially-decaying spatial distribution injected/depleted charge density in film accordance experimental observations, allowing extraction Debye length.

High mobility annealing of Transparent Conductive Oxides
To improve electrical properties a high temperature annealing treatment was applied to several transparent conductive oxides (TCO), namely tin doped indium oxide (ITO), Gaor Aldoped ZnO (ZnO:Al/Ga), ion beam assisted deposited (IBAD) ZnO:Ga and Ga doped zinc magnesium oxide (ZnMgO:Ga). All these films were grown by magnetron sputtering. During the annealing process all TCO films were capped wit...
