Abstract


Prin tratament termic (TT) la temperatura de 970 K, 1070 K și 1170 K timp de 6 ore a nanocristalelor Ga2S3, suprafața acestora se acoperă cu un strat de oxid Ga2O3, structura și grosimea cărora depind de durata TT. Stratul de oxid este compus din nanoformațiuni insulare poroase, care sunt alcătuite din nanofire și nanocristalite. Dimensiunile nanocristalitelor se micșorează la majorarea temperaturii de călire de la 1070 K la 1170 K.

SYNTHESIS AND MORPHOLOGY STUDY OF β-Ga2O3-Ga2S3 STRUCTURES

The heat treatment (TT) of Ga2S3 nanocrystals at temperatures of 970 K, 1070 K and 1170 K duration of 6 hours forms an oxide film of Ga2O3 on the crystal surface, the structure and thickness of which depends on the duration of heat treatment. The oxide layer consists of porous island nanoforms in the form of nanofibers and nanocrystals. The nanocrystalline size decreases with an increase in heat treatment temperature from 1070 K to 1170 K.


Keywords


heat treatment, nano-porous island formations, nanowires, nanocrystallites, morphology of the semiconductor structural surface.
