Features of Radiative Recombination of Iron-doped Gallium Antimonide

MIHALACHE, A. (Tehnica UTM, 2019)

We report on the results of the studies of the features of radiative recombination of iron-doped gallium antimonide at T = 2 K, in the absence of an external magnetic field. Specimens were prepared by a modified method of ...
Mecanismele de împrăştiere a purtătorilor de sarcină în antimonidul de galiu nedopat

MIHĂLACHE, A. (Editura U.T.M., 2010)

În această lucrare sau studiat efectele galvanomagnetice pentru antimonidul de galiu nedopat pentru un interval de temperaturi (4,2÷300 K) şi un interval de concentraţii (NA-ND) (1,5•1016÷5•1019 cm-3). Au fost studiate ...
Mössbauer Effect in 57Fe-doped Gallium Antimonide

MIHALACHE, A. (Tehnica UTM, 2019)

The work offers for discussion the results of investigations of absorption spectra (gamma-ray nuclear resonance) of gallium antimonide doped with 57Fe isotope in the concentration range of the atomic mass of 1–3%, within ...
Particularitățile relaxării spinului electronilor în antimonidul de galiu dopat cu fier

GHEORGHIȚĂ, Andrian; GHEORGHIȚĂ, Eugen; GUȚULEAC, Leonid; MIHĂLACHE, Alexei (Tehnica UTM, 2014)

The present paper analyzes the influence of iron upon mechanisms of the spin relaxation in the gallium antimonide, doped with iron in concentrations of up to 3% at. It is demonstrated, that the for low concentrations of ...
Particularităţile Efectelor Optice în Antimonidul de Galiu Dopat cu Nichel

GHEORGHIŢĂ, E.; GUŢULEAC, L.; MIHĂLACHE, A.; MELINTE, V.; CARAMAN, M.; PALACHI, L. (Technical University of Moldova, 2015)

The particularities of gallium antimonide optical effects doped with nickel in various concentrations were investigated. Depending on the concentration of nickel it was experimentally registrated a displacement of spectra ...

În lucrare se analizează particularitățile proprietăților fizice ale antimonidului de galiu dopat cu nichel pentru un diapazon vast de concentrații, până la 3% atomare și temperaturi (2÷300)K. Din analiza în ansamblu a ...
Relaxarea de spin în monocristalele de antimonid de galiu dopate cu fier

GHEORGHIŢĂ, Eugen; ERMALAI, Felicia; CANŢER, Valeriu (Technical University of Moldova, 2009)

In AIIIBV chemical combinations family, gallium antimonide is a material with unusual physical properties. Behavior of the transition elements like Iron, Chromium, Manganese, Nickel in various AIIIBV combinations is a ...
Structura spectrelor de iradiere a antimonidului de galiu dopat cu stibiu

GHEORGHIŢĂ, Eugen; GHEORGHIŢĂ, Andrian; ZLOTEA, Olga; POSTOLACHI, Igor (Technical University of Moldova, 2011)

In the present paper it is analyzed, using the Alentz-Fox method, the structure of the radiation spectrum of gallium antimonide doped with antimony at 2K temperature in absence of the external magnetic field. It is ...
Structura Spectrelor de Iradiere ale Antimonidului de Galiu Dopat cu Fier pentru Diapazonul Spectral (0,8÷0,812)Ev

GHEORGHIŢĂ, Eugen; GUŢULEAC, Leonid; MELINTE, Victoria (Technical University of Moldova, 2009)

Antimonidul of gallium is the family of materials with semiconductor properties. It has unusual properties and is less investigated compared to other combinations. In considering the work once the radiation spectra of ...
