含激子和极化激元的超导性
Superconductivity with excitons and polaritons
摘要：
与电子的费米气体共存的激子极化激元的玻色-爱因斯坦凝聚体最近被提出作为实现室温超导性的有希望的系统[Phys. Rev. Lett.，104，106402（2010）]。为了找到激子和激子-极化激元介导的超导电性的最佳条件，我们研究了由激子和激子-极化激元凝聚体介导的库珀对的电子之间的吸引机制，并分析了下面的间隙方程。我们具体解决微腔与嵌入式n-掺杂量子阱以及耦合量子阱托管空间间接激子的冷凝物，与二维电子气接触。我们表明，这些特殊的玻色-费米混合物中的相互作用的工程是复杂的，有时违反直觉，但留下了很大的自由优化，使有望实现高温超导多层半导体结构。
英文摘要：
A Bose--Einstein condensate of exciton polaritons coexisting with a Fermi gas of electrons has been recently proposed as a promising system for realisation of room-temperature superconductivity [Phys. Rev. Lett., 104, 106402 (2010)]. In order to find the optimum conditions for exciton and exciton-polariton mediated superconductivity, we study the attractive mechanism between electrons of a Cooper pair mediated by the exciton and exciton-polariton condensate and analyze the gap equation that follows. We specifically address microcavities with embedded n-doped quantum wells as well as coupled quantum wells hosting a condensate of spatially indirect excitons, put in contact with a two-dimensional electron gas. We show that engineering of the interaction in these peculiar Bose-Fermi mixtures is complex and sometimes counterintuitive, but leaves much freedom for optimization, making promising the realization of high-temperature superconductivity in multilayer semiconductor structures.
