研究目的
Investigating the micro structural and optical properties of Ferrous Selenide (FeSe) thin films prepared by Electron beam evaporation technique and their characterization at various annealing temperatures.
研究成果
The FeSe thin films deposited using Electron beam deposition method showed tetragonal crystal structure. The SEM and AFM studies show cluster of porous morphology. The optical studies revealed that thickness and roughness of surface is directly related to the temperature changes during the film deposition.
研究不足
The study is limited to the characterization of FeSe thin films prepared by electron beam evaporation technique and does not explore other deposition methods or materials.
1：Experimental Design and Method Selection:
FeSe thin films were prepared by electron beam evaporation technique using a HINDHI-VAC vacuum unit. The mixture of spectroscopically pure Ferric nitrate and Selenium di oxide was pressed into pellets and used as the source material for evaporation.
2：Sample Selection and Data Sources:
The films were deposited on glass substrates at different annealing temperatures (RT, 100°C, 200°C, and 300°C).
3：List of Experimental Equipment and Materials:
HINDHI-VAC vacuum unit (model: 12A4D), electron beam power supply (model: EBG-PS-3K), spectroscopically pure Ferric nitrate (99.99%), Selenium di oxide (SeO2).
4：99%), Selenium di oxide (SeO2).
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The pelletized FeSe targets were heated by means of an electron beam. The evaporated species from FeSe pellet were deposited as thin films on the substrates in a pressure of about 1x 10-5 mbar.
5：Data Analysis Methods:
X-ray diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and optical transmittance measurements were used to analyze the films.
