Current research concerns experimental investigation
of mesoscopic phenomena and phase coherence and electron
spin effects in semiconductor microstructures and other
submicron electronic devices. This work includes device
nanofabrication, low-noise electron transport measurement,
and characterization of quantum coherence by observing
transport effects such as localization, quantization,
and conductance fluctuations. Much of this work has
focused on clean, ballistic semiconductor structures,
such as chaotic quantum dots, with more recent work
emphasizing novel fabrication approaches and systems,
effects of electron spin, measurements of electron
decoherence, and potential applications of nanostructures
to quantum information and quantum computing.
Some recent projects in the group have investigated:
Electron phase coherence in quantum dots; coulomb blockade
effects other many-body effects in quantum dots; experiments
in quantum chaos; adiabatic charge pumping and geometric
phase effects in mesoscopics; coherence effects in
carbon nanotubes; spin effects in mesoscopics; and
experimental schemes for quantum computing and quantum
information processing in the solid state.
