Harmonic-potential traps for indirect excitons in coupled quantum wells
We explain our method of creating an in-plane harmonic potential for indirect excitons in coupled quantum wells, which has been developed for experiments on Bose condensation of excitons in two dimensions, although this method may also be used for trapping a two-dimensional electron gas. The indirect excitons in our coupled quantum wells exhibit a Stark shift of over 60 meV and lifetime of appr...
متن کاملTwo-dimensional snowflake trap for indirect excitons.
We present experimental proof of principle for two-dimensional electrostatic traps for indirect excitons. A confining trap potential for indirect excitons is created by a snowflake-shaped electrode pattern. We demonstrate collection of indirect excitons from all directions to the trap center and control of the trap potential by voltage.
متن کاملTwo-dimensional electrostatic lattices for indirect excitons
We report on a method for the realization of two-dimensional electrostatic lattices for excitons using patterned interdigitated electrodes. Lattice structure is set by the electrode pattern and depth of the lattice potential is controlled by applied voltages. We demonstrate square, hexagonal, and honeycomb lattices created by this method.VC 2012 American Institute of Physics. [doi:10.1063/1.368...
