Electron-hole cuprates for a possible Bose condensation?

Bose condensation, by promoting quantum behavior from the microscopic to the macroscopic world, can produce some spectacular effects: like include superconductivity, superfluidity, and coherent matter waves. This work proposes to achieve the Bose condensation of bound electron-hole pairs (excitons) in a solid at a temperature that is high compared to other Bose condensates. The route we will explore to achieve a BEC of bound excitons utilizes a modulation-doped “infinite-layer” CuO2-based compound. Using a molecular-beam epitaxy we will grow bilayer (or trilayer) of SrCuO2/La2CuO4 thin films. Structural and electrical data will be discussed.
