Abstract:
A phase-change oscillator and pulse generator, and related methods, are provided. The phase-change oscillator and pulse generator can include a capacitor, a switching element coupled in parallel connection with the capacitor, and a resistor coupled in series with the switching element and configured to supply a bias voltage to the switching element. The switching element can have a low-resistance state in a liquid-phase and a high-resistance state in a solid phase. In addition, the switching element can have a negative thermal coefficient of resistance. In an aspect, the switching element comprises a wire of a semiconducting material having negative thermal coefficient of resistance, such semiconducting material can be doped n-type or p-type. In an aspect, the liquid-phase is a molten state of the wire and the solid-phase is a solid state of the wire. An oscillatory signal is based at least on transitioning between the molten state and the solid state.
