Sliding modes in finite-time control systems with variable structure
(WORLD SCIENTIFIC AND ENGINEERING ACAD AND SOC, 2007)
This paper proposes a method for the organization of real sliding movements, which are caused by finite switching frequency of control systems. In one of two proposed structures for the organization of sliding modes, the ...
The polarizability and the photoionization cross-section under the external fields for donor impurities in quantum well-wire
(WILEY-V C H VERLAG GMBH, 2007)
In this study, we have calculated the donor impurity binding energy, donor impurity related photoionization cross-section and polarizability in symmetric GaAs/Ga1-xAlxAs quantum well-wire as a function of the impurity ...
Broadband asymmetric quantum-well infrared photodetector in long-wavelength infrared range (LWIR)
(IEEE, 2007)
A theoretical investigation of a GaAs-AlGaAs infrared detector consisting of three asymmetric quantum wells is presented. Each quantum well is sensitive to yield absorption and a photoresponse at peak wavelengths of 8 pro, ...
