Atomic resolution imaging at 2.5 GHz using near-field microwave microscopy
, 2010 Atomic resolution imaging is demonstrated using a hybrid scanning tunneling/near-field microwave microscope (microwave-STM). The microwave channels of the microscope correspond to the resonant frequency and quality factor of a coaxial microwave resonator,

Non-linear magnetotransport in microwave-illuminated two-dimensional electron systems
, 2008 We study magnetoresistivity oscillations in a high-mobility two-dimensional electron system subject to both microwave and dc electric fields. First, we observe that the oscillation amplitude is a periodic function of the inverse magnetic field and is ...
