Abstract EN
The indium selenium (InSe) bilayer thin films of various thickness ratios, InxSe(1-x) (x = 0.25, 0.50, 0.75), were deposited on a glass substrate keeping overall the same thickness of 2500 Ǻ using thermal evaporation method under high vacuum atmosphere.
Electrical, optical, and structural properties of these bilayer thin films have been compared before and after thermal annealing at different temperatures.
The structural and morphological characterization was done using XRD and SEM, respectively.
The optical bandgap of these thin films has been calculated by Tauc’s relation that varies within the range of 1.99 to 2.05 eV.
A simple low-cost thermoelectrical power measurement setup is designed which can measure the Seebeck coefficient “S” in the vacuum with temperature variation.
The setup temperature variation is up to 70°C.
This setup contains a Peltier device TEC1-12715 which is kept between two copper plates that act as a reference metal.
Also, in the present work, the thermoelectric power of indium selenide (InSe) and aluminum selenide (AlSe) bilayer thin films prepared and annealed in the same way is calculated.
The thermoelectric power has been measured by estimating the Seebeck coefficient for InSe and AlSe bilayer thin films.
It was observed that the Seebeck coefficient is negative for InSe and AlSe thin films.
