Trapping indirect excitons in a GaAs quantum-well structure with a diamond-shaped electrostatic trap.
We report on the principle and realization of a new trap for excitons--the diamond electrostatic trap--which uses a single electrode to create a confining potential for excitons. We also create elevated diamond traps which permit evaporative cooling of the exciton gas. We observe the collection of excitons towards the trap center with increasing exciton density. This effect is due to screening ...

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...
متن کاملExcited states of ring-shaped (InGa)As quantum dots in a GaAs/ (AlGa)As quantum well
By studying the resonant tunneling of electrons through self-assembled ring-shaped InGa As quantum dots embedded in the quantum well of an AlGa As/GaAs/ AlGa As heterostructure, we find evidence for the existence of excited states of the quantum dots which exhibit a 2pz-like character along the growth direction z. The states are investigated by magnetotunneling spectroscopy with magnetic fields...
