Definirea parametrilor gropilor cuantice utilizând metode optice nedistructive

DOROGAN, Andrei; DOROGAN, Valerian; SÎRBU, Nicolae; ZALOMAI, Victor (Universitatea Tehnică din Cluj-Napoca, 2015)

Anizotropia proprietăţilor optice (birefringenţa şi fenomenul de giraţie) este depistată în straturilor cu gropi cuantice. Structura neideală afectează spectrele optice, ceea ceduce la lărgirea neomogenă a frecvenței de ...
Definition of optical parameters of quantum wells using non-destructive methods

DOROGAN, A.; DOROGAN, V.; SÎRBU, N.; ZALOMAI, V. (Romanian Inventors Forum, 2015)

A digital method was developed to study the polarization dependency of reflectivity spectra of quantum wells. The method permits to determine more accurate the energy of quantum transitions and subsequent calculation of ...
Optical Modes Separator (Te, Tm) Based On In0.3Ga0.7As/GaAs Heterostructures With Quantum Wells

SÎRBU, N.; DOROGAN, A.; VIERU, T.; KAPON, E.; MEREUŢA, A. (Romanian Inventors Forum, 2011)

The study of luminescence, absorption and reflection spectra of In0.3Ga0.7As/GaAs heterostructures with quantum wells was made for determining fundamental electronic states of polariton excitons in quantum wells. The ...
