The effect of substrate and post annealing temperature on the electrical properties of polycrystalline InSe thin films

1999-06-01
The correlation between the electrical properties of vacuum evaporated InSe thin films and the growth conditions as well as post depositional annealing has been investigated. The electrical properties of the deposited films have been studied in the temperature range of 50-320 K. The donor levels present in the InSe films have been analysed by applying the single donor-single acceptor model to the electrical data.

Investigation of structural and optical parameters of Cu-Ag-In-Se thin films deposited by thermal evaporation method
Gullu, H. H.; CANDAN, İDRİS; COŞKUN, EMRE; Parlak, Mehmet (2015-01-01)
Annealing effect on the structural and optical properties of the quaternary Cu-Ag-In-Se thin film deposited by the thermal evaporation has been investigated. The evaporation source was prepared by using vertical Bridgman-Stockbarger crystal growth system. Structural analysis indicated that annealing the films following to the deposition resulted in the changes from amorphous to polycrystalline phase with the preferred orientation along (1 1 2) direction. In order to determine the optical properties of the t...
The Effects of High Frequency RF Capacitively Coupled Plasma on Tensile Strain and Functional Groups of PAN based Carbon Fiber
Erözbek Güngör, Ümmügül (2014-04-25)
In this study, high frequency (40.68 MHz) RF capacitively coupled discharge was used to modify tensile strain and chemical structure of unsized PAN-based carbon fiber under different RF powers, pure nitrogen gas pressures and exposure times. The plasma parameters were diagnosed by using single and double Impedans Langmuir probe techniques to understand physics of high frequency RF-CCP treatment processes. The power range was P = 50-200 Watt and the pressure range was p ≈ 0.1-0.8 Torr. The measured plasma pa...
The Effect of Rolling and Aging on Mechanical and Tribological Properties in B4C Particle Reinforced Al7075 Matrix Composites
Demir, Mehmet Emin; Çelik, Yahya Hışman; Kalkanlı, Ali (2022-01-01)
© 2022, King Fahd University of Petroleum & Minerals.Strengthening, heat treating, or rolling these alloys with different reinforcement particles positively affects the physical, mechanical and tribological properties. In this study, materials were produced by squeeze casting method by adding B4C particle to Al7075 alloy matrix in 4 different reinforcement ratios (4%, 8%, 10%, 12%). The physical, mechanical, and tribological properties of B4C/Al7075 composites were compared to the Al7075 alloy. In addition,...
Effect of post-processing heat treatment on the mechanical properties of inconel 718 fabricated by selective laser melting
Özer, Seren; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2020)
In this study, effect of the building direction and post-processing heat treatments on the microstructure and high temperature mechanical properties of as-fabricatedInconel 718 alloys have been investigated. Inconel 718 samples were fabricated in two different building directions such that their longitudinalaxes wereeither parallel (horizontally built) or perpendicular (vertically built) to the building plate. During the selective laser melting (SLM)process, some undesired features can...
Study on the Structural and Electrical Properties of Sequentially Deposited Ag-Ga-In-Te Thin Films
Coskun, EMRE; Gullu, H. H.; Parlak, Mehmet; Ercelebi, C. (2015-02-01)
The structural properties and electrical conduction mechanisms of Ag-Ga-In-Te thin films deposited by a combination of e-beam and thermal evaporation methods were studied for various annealing temperatures. Structural analysis showed the existence of InTe and InTe binary phases at the early stage of crystallization and monophase of AgGaInTe with the main orientation along (112) direction following the post-annealing at 400 C. The effects of the structural changes on electrical properties and temperature dep...
