Applications for TCF Materials
The disclosed invention is a novel strategy for creating transparent conducting film (TCF) materials, which allows for tenability of conductance and transparency based on relevant physical parameters, carrier concentration, free carrier mass and thickness of the material. The class of materials possesses short electron mean free paths and more favorable sheet resistance dependence on film thickness; high electrical conductivity through metal-like carrier concentrations; and high transparency in VIS-IR range and deep-UV range. The reduced thickness increases the high volume throughput, mass production and down-scaling of feature sizes. The invention’s reliable, reproducible method of manufacturing is compatible with existing large volume production and low-cost equipment.
Application & Market Utility
This class of material can potentially replace indium tin oxide (ITO) as transparent conducting thin film. ITO is the mainstream transparent conductor currently dominating the market. The indium price has rapidly increased in recent years due to its limited natural abundance and increased demands from the display industry. The invention’s class of chemically inert materials has low toxicity compared to current ITO.
