Bound-continuum intersubband transition based optical nonlinearities in semiconductor quantum wells
(Solid State Phenomena, 1998)
The possibility is explored of obtaining resonantly enhanced nonlinear optical susceptibilities in semiconductor quantum wells with two bound states and the resonant state in continuum as the third state. This would ...
Intersubband resonant third harmonic generation in asymmetric semiconductor quantum wells
(Solid State Phenomena, 1998)
Possibilities for the systematic optimization of step-graded ternary alloys based quantum wells, in respect to third order nonlinear susceptibility ar resonance, are discussed. The use of this method is exemplified on the ...
Hysteretic Behavior of Elastic-plastic Beams Subjected to Cyclic Bending
(Jugoslovensko društvo za mehaniku - JDM, 1993)
In this paper, Preisach model for hysteresis behavior of elastic-plastic materials is extended to cyclic bending of beams.
Electronic structure and electron distribution in an inverse superatom calculated by self-consistent method
(Microelectronics Journal, 1990)
A full self-consistent procedure, applied to an inverse superatom strucuture is described. It is shown, both numerically and theoretically, that the electron concentration is large, but not maximal, the point of maximum ...
Resonantly enhanced bound-continuum intersubband second harmonic generation in optimized asymmetric semiconductor quantum wells
(Physica E: Low-dimensional Systems and Nanostructures, 1999)
A systematic procedure applied to a step-asymmetric quantum well in order to maximize intersubband bound–continuum second-order susceptibility is described. The possibility is explored of obtaining resonantly enhanced ...
Numeričko modeliranje diskontinualnih tokova / Numerical modelling of discontinuous flows
(Savezni hidrometeorloški zavod, 1994)
Operatori ekspertnog sistema za ocenu bezbednosti brana / Operators of an Expert System for Safety Evaluation of Dams
(Univerzitet u Beogradu, Ekonomski fakultet, 1996)
U radu je prikazan specifičan i originalan način prevazilaženja odredjenih teškoća, koje se odnose na konkretne uslove vezane za stanje u oblasti bez-bednosti brana u Srbiji, koji ovu materiju svrstavaju u tzv. "fuzzy" ...
Preisach Model for Cyclic Bending of Elastoplastic Beams
(Elsevier, 1996)
In the present paper, the Preisach model, already successfully implemented for the problem of axially loaded members, has been extended to the cyclic bending of elasto-plastic beams. Starting from Hooke's and St. Venant's ...
Influence of the self-consistent potential on absorption cross section in semiconductor quantum dot
(Solid State Phenomena, 1998)
In this paper the intersubband optical absorption cross sections are calculated for spherically symmetric semiconductor quantum dot (QD), made of GaAs-Al0.3Ga0.7As with the influence of the accumulated charge in the well ...
