Direct measurement of the maximum tunnel rate in a radio frequency single electron transistor operated as a microwave mixer

, 2004
By operating the radio frequency single electron transistor (rf-SET) as a mixer we present measurements in which the RC roll-off of the tunnel junctions is observed at high frequencies. Our technique makes use of the non-linear rf-SET transconductance to
