Quantum paraelectric varactors for radio-frequency measurements at mK temperatures

Autor: Apostolidis, P., Villis, B. J., Chittock-Wood, J. F., Baumgartner, A., Vesterinen, V., Simbierowicz, S., Hassel, J., Buitelaar, M. R.

Radio-frequency reflectometry allows for fast and sensitive electrical readout of charge and spin qubits hosted in quantum dot devices coupled to resonant circuits. Optimizing readout, however, requires frequency tuning of the resonators and impedanc

Defect detection in nano-scale transistors based on radio-frequency reflectometry

Autor: Villis, B. J., Orlov, A. O., Jehl, X., Snider, G. L., Fay, P., Sanquer, M.

Radio-frequency reflectometry in silicon single-electron transistors (SETs) is presented. At low temperatures (<4 K), in addition to the expected Coulomb blockade features associated with charging of the SET dot, quasi-periodic oscillations are obser

Shallow donor impurities in silicon, once frozen out at low temperature, share many properties in common with free hydrogen atoms [1]. They have long been the subject of spectroscopic investigation, but it is only very recently [2,3] that it has been
