过渡金属氧化物异质结构中的电子空穴液体

Electron-Hole Liquids in Transition Metal Oxide Heterostructures

Andrew J. Millis, Darrell G. Schlom

摘要:

适当设计的过渡金属氧化物异质结构,涉及小带隙莫特绝缘体被认为是支持空间分离的电子和空穴气体在平衡。有利于激子态形成的空间分离和载流子密度是可实现的。激子态可能表现出潜在的新颖性质。给出了能量估计,讨论了候选材料系统,并提到了大光伏效应的可能性

英文摘要:

Appropriately designed transition metal oxide heterostructures involving small band gap Mott insulators are argued to support spatially separated electron and hole gasses at equilibrium. Spatial separations and carrier densities favoring the formation of excitonic states are achievable. The excitonic states may exhibit potentially novel properties. Energetic estimates are given, candidate material systems are discussed, and the possibility of large photvoltaic effects is mentioned
