Single-Electron Capacitance Spectroscopy of Individual Dopants in Silicon
M. Gasseller, R. Loo, J. F. Harrison +3
Motivated by recent transport experiments and proposed atomic-scale semiconductor devices, we present measurements that extend the reach of scanned-probe methods to discern the pro…
Scanning-probe spectroscopy of semiconductor donor molecules
I. Kuljanishvili, C. Kayis, J. F. Harrison +5
Semiconductor devices continue to press into the nanoscale regime, and new applications have emerged for which the quantum properties of dopant atoms act as the functional part of…
Tunneling images of a 2D electron system in a quantizing magnetic field
I. J. Maasilta, Subhasish Chakraborty, I. Kuljanishvili +2
We have applied a scanning probe method, Subsurface Charge Accumulation (SCA) imaging, to resolve the local structure of the interior of a semiconductor two-dimensional electron sy…
Direct observation of micron-scale ordered structure in a two-dimensional electron system
I. J. Maasilta, Subhasish Chakraborty, I. Kuljanishvili +2
We have applied a novel scanned probe method to directly resolve the interior structure of a GaAs/AlGaAs two-dimensional electron system in a tunneling geometry. We find that the a…
Modeling Subsurface Charge Accumulation Images of a Quantum Hall Liquid
S. H. Tessmer, G. Finkelstein, P. I. Glicofridis +1
Subsurface Charge Accumulation imaging is a cryogenic scanning probe technique that has recently been used to spatially probe incompressible strips formed in a two-dimensional elec…
Imaging of Low Compressibility Strips in the Quantum Hall Liquid
G. Finkelstein, P. I. Glicofridis, S. H. Tessmer +2
Using Subsurface Charge Accumulation scanning microscopy we image strips of low compressibility corresponding to several integer Quantum Hall filling factors. We study in detail th…
