Observation of Inter-Valley Gap Anomaly of Two Dimensional electrons in Silicon
K. Lai, W. Pan, D. C. Tsui +3
We report here a systematic study of the energy gaps at the odd-integer quantum Hall states and 5 under tilted magnetic (B) fields in a high quality Si two-dimensional elect…
Indirect Exchange Interaction in Fully Metal-Semiconductor Separated SWCNTs Revealed by ESR
M. Havlicek, W. Jantsch, Z. Wilamowski +8
The ESR response from highly metal-semiconductor(M-SC) separated SWCNTs for temperatures T between 0.39 and 200 K is characteristically different for the two systems. The signal or…
The Two-flux Composite Fermion Series of Fractional Quantum Hall States in Strained Si
K. Lai, W. Pan, D. C. Tsui +3
Magnetotransport properties are investigated in a high-mobility two-dimensional electron system in the strained Si quantum well of a (100) Si_0.75Ge_0.25/Si/Si_0.75Ge_0.25 heterost…
Linear temperature dependence of conductivity in Si two-dimensional electrons near the apparent metal-to-insulator transition
K. Lai, W. Pan, D. C. Tsui +3
In a high mobility two-dimensional electron system in Si, near the critical density, cm, of the apparent metal-to-insulator transition, the conductivi…
Valley splitting of Si/SiGe heterostructures in tilted magnetic fields
K. Lai, T. M. Lu, W. Pan +6
We have investigated the valley splitting of two-dimensional electrons in high quality Si/SiGe heterostructures under tilted magnetic fields. For all the samples in our…
