RESEARCH STATEMENT | ||||||||||||||

Dr. Du’s research area and scholarly interests have been on the physics of low dimensional electron systems, especially on the fractional quantum Hall effect. The research work focuses on fundamental understanding of quantum mechanical properties of electrons in low dimensional and nanoscale semiconductor structures and devices. Here is an outline of current research topics. 2D and 1D electron systems provide both a clean laboratory for many-particle physics and a unique platform addressing emerging issues in spintronics and solid-state quantum information devices. Our recent research has been centered on these two themes and has been supported by DOE, NSF, and DARPA. The materials used are mainly GaAs/AlGaAs heterostructures and quantum wells, but also include Si and InGaAs depending on the physics involved. 1. Many-Particle Physics in Ultracold 2D Electron Systems Experiments in 2D electron system (2DES) can be turned by many “knobs”, and multitude many-particle electronic phases and phase transitions can be studied: fractional charged quantum fluid, Wigner lattices, Luttinger liquid, Stripes and liquid crystal-like phases, and Skyrmions, to name a few. Not unlike in AMO where Bose-Einstein condensation was discovered in ultracold atoms, the frontier of 2DES physics is on ultracold electrons. In collaboration with Columbia (Prof. Horst Stormer), Princeton (Prof. Dan Tsui), Stanford (Prof. Doug Osheroff), and funded by DOE, we have been pursuing a major research project (submillikelvin demagnetization refrigerator for solid state research) for experiments on ultracold electrons in low-D semiconductors and nanostructures. One of the objectives is to searching for exotic many-particle electronic states that obey non-Abelien statistics, but there are much more: cooling electrons to lower than few millikelvin becomes increasingly relevant to general issues of quantum decoherence and phase transitions in electronic systems including mesoscopic metals, quantum dots, and quantum magnets. With the capability to cool 2D electrons to lower temperature, we will develop two important tools for studying many-particle states: tunneling into edge of the quantum fluid and NMR for nuclear spins in the host materials (which in turn reflect the spin states in the 2DES). 2. Novel DC Transport Phenomena and Effect in a AC Driven Quantum Well Electrical transport of a 2DES exposed to a high frequency (from GHz to THz) driving electromagnetic wave is directly relevant to emerging issues concerning spintronics and quantum information processing. Fundamentally new phenomena of magnetoresistance oscillation and zero-resistance/zero-conductance have been discovered in our lab during the recent years (Phys. Today, Search & Discovery April 2003). We will continue to explore this new effect and its physics. One ongoing project is to develop a scanning Hall probe microscopy for simultaneously imaging the electrical current pattern formation and measuring dc transport. If this is successful we will be able to study the domain states proposed by theories in this novel effect. 3. Spin and Magnetic Phenomena Spin and spin-interaction effects are the fundamental properties in 2D electron and 2D hole systems in semiconductors. Controlling spin polarization via electrical gates or microwave excitations is part of the research effort in my group. We have studied some interesting phenomena in magnetic alloys, such as DyAs, and more recently InGaAs. 4. Si-Based Nanoelectronics Supported by a DARPA grant (University of Illinois) “Wavefunction engineering of individual donors for Si-based quantum computers” we have been participating in a quantum information project. The goal of this project is to place individual phosphorous (P) donors into silicon with atomic precision, and to demonstrate electrical control over the coupling between them as a function of their spin states. Our group is responsible for quantum transport measurement of the Si-nanostructures produced by this atom-scale STM patterning technique. We have shown that an ultradense (about 3 orders of magnitude higher than usual 2DES in GaAs) P donor sheets can be formed using this technique, and transport shows a metallic conduction at low temperatures. Recently a nano-size Aharanov-Bohm ring has been fabricated and verified by our magnetotransport. In summary, our research will continue to focus on the many-particle physics in lower dimensional electron systems, one of the most important and challenging areas in condensed matter sciences. | ||||||||||||||
