Abstract

We first time demonstrate an electrolyte/semiconductor junction diode formed on single-crystal gallium oxide (β-Ga2O3) exhibiting Schottky-type behavior and its ability in single base mismatch detection of let 7a and let 7f miRNA at picomolar (pM) level. The diode has exhibited good electrical characteristics and its ideality factor[1], threshold potential and Schottky barrier height could be calculated from its I-V characteristics. A liquid junction diode has been demonstrated for multi biosensing application and 100 pM target miRNA (let 7a) could be detected from single base mismatch let 7f through the resistivity shift with high specificity.
