ZnGa2O4 Targets for Pulsed Laser Deposition

Introduction to the properties of ZnGa2O4 and its use in thin film form

Zinc gallate (ZnGa2O4) is a wide bandgap material with a spinel structure that has attracted attention for its potential applications in various fields such as optoelectronics, photocatalysis, and photovoltaics. As a transparent conductive oxide (TCO) material, ZnGa2O4 has excellent optical and electrical properties that make it a promising alternative to other TCO materials such as indium tin oxide (ITO) and aluminum-doped zinc oxide (AZO).

Optical and Electronic Properties of ZnGa2O4

ZnGa2O4 has a wide bandgap of approximately 4.2 eV, which makes it transparent in the visible and ultraviolet regions of the electromagnetic spectrum. This property, combined with its high electrical conductivity, makes ZnGa2O4 an attractive candidate for use as a transparent electrode in various optoelectronic devices such as solar cells, light-emitting diodes (LEDs), and flat panel displays.

Comparison to Similar Materials

Compared to other TCO materials such as ITO and AZO, ZnGa2O4 has several advantages including higher conductivity, better stability, and lower toxicity. ZnGa2O4 also has a higher work function compared to ITO, which makes it a better candidate for use in hole transport layers in organic solar cells.

Crystal Structure of ZnGa2O4

ZnGa2O4 has a cubic spinel crystal structure with a lattice constant of approximately 8.09 Å. The crystal structure of ZnGa2O4 is similar to that of other spinel materials such as MgAl2O4 and Fe3O4.

Typical Substrates for Epitaxial Growth of ZnGa2O4

Some of the substrates that support epitaxial growth of ZnGa2O4 include sapphire, MgAl2O4, and SrTiO3. These substrates have similar lattice parameters and crystal structures to ZnGa2O4, which enables high-quality epitaxial growth of ZnGa2O4 thin films.
