Contactless measurement of electrical conductance of a thin film of amorphous germanium
T. S. Mentzel, K. MacLean, M. A. Kastner
We present a contactless method for measuring charge in a thin film of amorphous germanium (a-Ge) with a nanoscale silicon MOSFET charge sensor. This method enables the measurement…
Charge transport in arrays of PbSe nanocrystals
T. S. Mentzel, V. J. Porter, S. Geyer +3
We report electrical transport measurements of arrays of PbSe nanocrystals forming the channels of field effect transistors. We measure the current in these devices as a function o…
The Intrinsic Origin of Spin Echoes in Dipolar Solids Generated by Strong Pi Pulses
Dale Li, Yanqun Dong, R. G. Ramos +4
In spectroscopy, it is conventional to treat pulses much stronger than the linewidth as delta-functions. In NMR, this assumption leads to the prediction that pi pulses do not refoc…
Measurements of the spin relaxation rate at low magnetic fields in a quantum dot
S. Amasha, K. MacLean, Iuliana Radu +4
We measure the relaxation rate of a single electron spin in a quantum dot at magnetic fields from 7 T down to 1.75 T, much lower than previously measured. At…
