Abstract: A reconfigurable phase change device with methods for operating and forming the same are disclosed. An example device can comprise a reconfigurable layer comprising a phase change material, and a set of contacts connected with the reconfigurable layer. The set of contacts can comprise at least a first contact, a second contact, and a third contact. The device can comprise at least one control element electrically coupled with one or more of the set of contacts. The at least one control element can be configured to supply a first control signal to one or more of the set of contacts. The first control signal can be configured to modify a first portion of the reconfigurable layer thereby isolating the first contact from the second contact and the third contact.

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.
