We have directly measured, under operating conditions, the distributions of carrier densities and temperatures in a gain-clamped semiconductor optical amplifier designed for operation at 1.55 mum.
We introduce a new topological descriptor of a network called the density decomposition which is a partition of the nodes of a network into regions of uniform density.
The negatively charged exciton (X(-)) is observed to strongly couple with the microcavity (MC)-confined photons in a GaAs quantum well containing a two-dimensional electron gas with 0 n(e) 3 x 10
Since the deduction of a discontinuity in the density functional exchange-correlation potential v sub (xc) across the energy gap [1,2], Godby et al.
The field-effect mobility in crystalline organic FETs is known to be an order of magnitude larger than the mobility observed in thin-film OFETs.
We report measurements of the physical properties of the 30K superconductor Ba sub (0.6) K sub (0.4) BiO sub 3, including upper and lower critical fields and normal state susceptibility.
Variable-density one-dimensional electron gas was realized in a T-shaped quantum wire with an FET gate.
There is controversy as to whether a one-dimensional (1D) electron gas can spin polarize in the absence of a magnetic field.
We observe density-induced 90degrees rotations of the anisotropy axes in transport measurements at half-filled high Landau levels in the two dimensional electron system, where stripe states are pro
Background: A rapid growth in private dentistry in China has been observed during recent years.
