Abstract(in English) | Compound semiconductor based single electron devices having novel gate structures have been proposed and investigated. Schottky wrap gate(WPG) configruation was applied to AlGaAs/GaAs quasi one-dimensional wire to form potential barrier and to control potential of quantum dot within the wire. Single electron transistor(SET) operation as well as the maximum voltage gain larger than unity was achieved in the WPG SET. Furthermore, Schottky WPG controlled SET was succesfully fabricated directly onto an InAlAs/InGaAs/InAlAs ridge quantum wire grown by selective MBE. Fabricated InGaAs WPG SET showed clear Coulomb blockade conductance oscillations up to 30K with Coulomb gap of 10mV. These results indicate the proposed WPG structure is useful to realize compound semiconductor SETs. |
