Abstract

This invention provides a field effect transistor type hydrogen sensor, comprising a substrate unit made from a semiconductor material, an electron flowing unit formed on the substrate unit with a semiconductor material for electrons to flow, and an electric control output unit made from a Schottky contact layer and an electrode electrically connected with the Schottky contact layer. The electrode comprises a gate terminal made from Pd, and a source terminal and a drain terminal made from Au-Ge-Ni alloy. When hydrogen comes into contact with the gate terminal, the electricity of the gate terminal is changed, so as to regulate electron flowing density in the electron flowing unit, thereby changing the current-voltage characteristics of the field effect transistor type hydrogen sensor, and thus sensing the environmental hydrogen concentration.
