DURIP DEVELOPING A CRYOGENIC MAGENTO-OPTICAL SYSTEM WITH NANOMECHANICAL CONTROLS OF VAN DER WAALS QUANTUM MATERIALS
Abstract
Van der Waals (vdW) quantum materials have emerged as highly versatile and functional material platforms for both studying fundamental science and developing quantum technologies. One unique aspect of vdW crystals is that their physical properties are very sensitive to interlayer coupling and lattice geometry. Tuning these parameters can be realized through nanomechanical controls. One such control is hydrostatic pressure, which controls the interlayer separation and stacking. Another such control is uniaxial strain, which provides additional tuning of lattice constant and crystal symmetry. Currently, the in-situ nanomechanical control of vdW crystals at cryogenic temperatures with a vector magnet is not available. Since the nano-mechanical control systems is not rotatable, the vector magnet provides directional control of magnetic fields. This is critical for the investigation and manipulation of the multiple degrees of freedom of electrons in arbitrary orientations. Here, we propose to acquire and develop a system that combines magnetooptical spectroscopy with in-situ high pressure and strain control of vdW crystals at cryogenic temperatures and under direction-controlled magnetic fields.
