摘要
Single-electron transistors can be fabricated in AlGaAs/GaAs heterostructures in different ways. Besides conventional ways to produce lateral and vertical tunneling structures the overgrowth of patterned substrates is presented as a new method to obtain complete transistors. Single-electron tunneling through single and coupled quantum dots is shown and the possibilities of doing spectroscopy of electronic states are discussed.
