Nonlocal Differential Resistance in AlO/KTaO Heterostructures
Patrick W Krantz, Venkat Chandrasekhar
Local and nonlocal differential resistance measurements on Hall bars defined in AlO/KTaO heterostructures show anomalous behavior that depends on the crystal orientation an…

Observation of zero-field transverse resistance in AlO/SrTiO interface devices
P. W. Krantz, V. Chandrasekhar
Domain walls in AlO/SrTiO (ALO/STO) interface devices at low temperatures give a rise to a new signature in the electrical transport of two-dimensional carrier gases formed…

A Mach-Zehnder interferometer based tuning fork microwave impedance microscope
Z. Liu, P. W. Krantz, V. Chandrasekhar
We describe here the implementation of an interferometer-based microwave impedance microscope on a home-built tuning-fork based scanning probe microscope (SPM). Tuning-fork based S…
