Using an ultrafast laser to excite 2D nanostructures, and coherent extreme ultraviolet light to detect the resulting acoustic response, we observe and characterize the shortest-wavelength (35 nm) surface acoustic waves to date.
We have measured the room temperature response of nanoscale semiconductor Hall crosses to local applied magnetic fields under various local electric gate conditions using scanning probe microscopy. Near-surface quantum wells of AlSb/InAs/AlSb, located just 5 nm from the heterostructure surface, allow very high sensitivity to localized electric and magnetic(More)
