Imaging of electrically controlled van der Waals layer stacking in 1T-TaS₂.

ABSTRACT: Van der Waals materials exhibit a variety of states that can be switched with low power at low temperatures, offering a viable cryogenic 'flash memory' required for the classical control electronics for solid-state quantum information processing. In 1T-TaS₂, a non-volatile metallic 'hidden' state can be induced from an insulating equilibrium charge-density wave ground state using either optical or electrical pulses. Given that conventional memristors form localized, filamentary channels which support the current, a key question for design concerns the geometry of the conduction region in highly energy-efficient 1T-TaS₂ devices. Here, we report in operando micro-beam X-ray diffraction, fluorescence, and concurrent transport measurements, allowing us to spatially image
