Title: Field-effect transistor
Inventor: FUJISHIRO HIRONORI
IPC: H01L29/778
Filed: 1990-06-25
Abstract: PURPOSE:To make the energy of some quantum levels of respective quantum levels of electrons increase and make the concentration of electrons occupying the quantum level decrease, by providing a potential barrier layer in or near a carrier feeding layer. CONSTITUTION:Ef, E0, E1, and E2 represent Fermi level, a base level of electron, a first excitation level of electron, and a second excitation level of electron respectively. the energies of the base level E0 and the first excitation level E1 of electron are scarcely varied even when providing a barrier layer 41. While the second excitation level E2 of electron is 188meV when providing no barrier, it comes to be 211meV, i.e., increases by 23meV when providing the barrier. The lower the order of a quantum level is, the higher the concentration of electrons occupying the quantum level comes. Therefore, the concentration of electrons occupying an overall system is dominated by the concentrations of electrons occupying the quantum levels of low orders. Thereby, the barrier layer 41 increases only the energy of the second excitation level, and the concentration of electrons occupying the second excitation level is made to decrease.
