Abstract:
1. A thin-film diode, comprising: a first contact of a material having a first conductivity type; a second contact of a material having a second conductivity type arranged co-planarly with the first contact; an undoped poly-silicon channel arranged between the first and second contacts resulting in the diode having an anode with capacitance and a cathode with capacitance, wherein only one of the anode capacitance and the cathode capacitance is non-zero at a given time; a metal gate arranged adjacent the channel such that the gate avoids overlapping the first and second contacts; and a voltage source electrically connected to the gate, the voltage source being operable either positively or negatively, wherein a polarity of the voltage source determines a gate bias polarity, the gate bias polarity determining which of the anode capacitance or the cathode capacitance is non-zero at the given time.
