Claim Text:
1. A semiconductor device, comprising: a hole transport layer having a first side and a second side, the hole transport layer comprising a material in which hole mobility is greater than electron mobility and having a first ionization potential and a first electron affinity; an electron transport layer having a first side and a second side, the electron transport layer comprising a material in which electron mobility is greater than hole mobility and having a second ionization potential and a second electron affinity, the second ionization potential being greater than the first ionization potential and the second electron affinity being greater than the first electron affinity, wherein the first side of the electron transport layer is directly interfaced to the second side of the hole transport layer; a first electrode directly interfaced to the first side of the hole transport layer; a second electrode directly interfaced to the first side of the hole transport layer and physically separated from the first electrode; and a gate electrode that is disposed between a substrate of the semiconductor device and the electron transport layer and is directly interfaced to the second side of the electron transport layer.
