Magneto-optics of layers of semiconductor quantum dots and nano-rings

Magneto-optical response of layers of semiconductor quantum dots and nanorings

In this paper a comparative theoretical study was made of the magneto-optical response of square lattices of nanoobjects dots and rings . Expressions for both the polarizability of the individual objects as their mutual electromagnetic interactions for a lattice in vacuum was derived. The quantum-mechanical part of the derivation is based upon the commonly used envelope function approximation. ...

Quantum Mechanics of Semiconductor Quantum Dots and Rings

The progress of semiconductor physics in the decade 1970-1980 is connected with gradual deviation from the electronic band structure of ideal crystal of Bloch picture (Bloch, 1928) where, unlike atomic world with its discrete and precisely defined, in the limits of uncertainty relation, energy levels, energy of bound electron is a multivalued function of momentum in the energy band and density ...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Nano-optoelectronics Based on Iii-v Semiconductor Quantum Dots

In this talk, I discuss the new physics and device applications provided by self-assembled quantum dots, in particular, with III-V compound semiconductor materials system. The quantum dots are the structures three-dimensionally confined and therefore provide quasi zero-dimensional electron gas system, where novel physics can be studied and improved device performance can be achieved, in particu...
