The matrix A (over the real field) is said to have the property P. if and only if every set of t columns of A is linearly independent. In this paper, for all positive integers q, we obtain necessary conditions on A* such that . (N × 2.) submatrix A** in A h

Book 2004 and lasers) and in daily life, in e. g. LED-based tra?c lights, CD-players, cash registers. The introduction of impurities, also in very small concentrations, in a semiconductor can change its optical and electrical properties entirely. This attribute of the semiconductor is utilized in the manifol

The High Doping Regime, is formed, which can move in the potential of the fixed ions of opposite charge. This level is ususally refered to as the metallic limit or the Mott transition , i.e., the electronic phase change from an insulating to a metallic behavior.

Introduction, de Broglie wavelength of the electrons can be achieved. We have accordingly advanced from the classical physics to a situation with structures in the quantum limit. The driving force for the effort behind this development is the potentiality to modify the electronic properties of the quantum structures by the confinement .
