Spin dynamics of shallow impurity electrons in the insulating phase of n-doped semiconductors are examined within framework of the scaling theory of disordered spin-1/2 Heisenberg antiferromagnet.
T HE theory of an electron stream flowing in a diode has received much attention; 1 - 1 3 because the tetrodes, pentodes and other modern tubes are cascade arrangements of individual diodes.
A simple mathematical proof is given of this result: In a plane diode with hot cathode and space charge, operated under a voltage whose variation with time is arbitrary, electron trajectories never
The electron transfer induced dimerization of spiro[4.2] heptadiene and the corresponding cleavage reaction of the [4+2]dimer have been investigated in polar solvents.
The primary process in photosynthesis is the conversion of light into electrochemical energy. This process occurs in a protein- pigment complex called the reaction center.
The radical cation (3+) of 9-methylenebicyclo[4.2.1]nona- 2,4,7- triene undergoes rapid intramolecular cyclization to generate an isomeric radical cation (15+) derived from a tetracyclic structure.
The radical cations of bicyclo[6.1.0]nonatriene (1a) and several derivatives (1b-1f) have been generated by photoinduced electron transfer in solution.
The self-assembly technique provides a synthetic method for positioning electron donor or acceptor molecules near an electrode surface.
An exact solution is obtained for the quantum-mechanical reflection and transmission coefficients for the electronic motion across the boundary of two different one-dimensional crystals, each desc
Ballistic transmission of electrons is possible in principle across the atomically abrupt epitaxial interfaces that can be formed between silicon and several metallic silicides.
