摘要
Inorganic liquid semiconductors are of interest in harsh radiological environments, flexible electronics, and for direct printing of semiconductor devices. Many elemental and compound liquid semiconductors exist, although the lowest melting point is observed for Se at 221 °C. Recently, reports of liquid Se-S systems have shown betavoltaic and alphavoltaic power generation as a liquid with a reduced melting point of 105 °C. Here, we show the ability to depress the melting point to 57 °C by using equal atomic fractions of selenium and iodine while maintaining semiconducting behavior. A heterojunction structure using ITO and n-GaN as the contacts was selected based on chemical compatibility and predicted band lineups. Electrical and optical measurements were used to deduce the electronic and transport properties of the mixture.
