Presentation Title: Transport properties of a germanium/silicon nanowire
Section: The Nano World II
Location: McCardell Bicentennial Hall, 216
Date & Time: Friday, April 19, 2013 - 11:35am - 11:50am
We present transport measurements of a germanium/silicon nanowire device in a dilution refrigerator with an electron temperature of ~100 mK. Using a lock-in measurement technique, we are able to observe excited states in the Coulomb-blockade regime of a single quantum dot created in the nanowire. In addition, we observe double quantum dot behavior in the nanowire. Germanium/silicon nanowires contain relatively low nuclear spin densities, making them promising candidates for spin qubits.
