Abstract
A thin film transistor (TFT) includes a hole transport layer having a first side and a second side and an electron transport layer having a first side and a second side. The first side of the electron transport layer is directly interfaced to the second side of the hole transport layer. The electron transport layer includes a material having greater ionization potential and greater electron affinity than the hole transport layer, thereby forming a hole barrier and an electron barrier at the junction between the electron transport layer and the hole transport layer. A channel in the TFT is created by current injected into the electron transport layer from a gate electrode rather than by an electrostatic field generated by voltage applied to the gate electrode. The accumulated charge density in the channel of the TFT can be significantly larger than what can be generated through field effect principle, therefore a much lower gate voltage is needed than in a conventional TFT.
