4.2 K sensitivity-tunable radio frequency reflectometry of a physically defined p-channel silicon quantum dot
Abstract We demonstrate the measurement of p-channel silicon-on-insulator quantum dots at liquid helium temperatures by using a radio frequency (rf) reflectometry circuit comprising of two independently tunable GaAs varactors. This arrangement allows observing Coulomb diamonds at 4.2 K under nearly...
