ABSTRACT

Tin selenide (SnSe) and copper indium diselenide (CuInSe2) compounds were synthesized by high temperature reaction method using combination of sealed ampoule (at relatively low pressure ~10-1 Pa without inert gas) and heating at specific temperature profile in rocking furnace. Powder X-Ray diffraction analysis showed that the products involved only single phases of SnSe and of CuInSe2 only. Using the reaction products as source materials, the SnSe and CuInSe2 thin films were vacuum-deposited on glass substrates at room temperature. Structural, elemental, surface morphological and optical properties of the as-deposited films were studied by X-Ray diffraction (XRD), energy dispersive X-Ray (EDX) analysis, field emission scanning electron microscopy (FESEM) and UV-Vis-NIR spectroscopy. Single phase of SnSe and CuInSe2 films were obtained by thermal evaporation technique from synthesized SnSe and CuInSe2 compound without further treatment.

 

Keywords: CuInSe; SnSe; solid state reaction; source material; thin films

 

ABSTRAK

Sebatian timah selenida (SnSe) dan kuprum indium diselenida (CuInSe2) telah disintesis pada tindak balas bersuhu tinggi menggunakan gabungan ampul yang ditutup kedap (pada kadar tekanan rendah ~10-1 Pa tanpa gas lengai) dan pemanasan pada profil suhu khusus dalam relau berayun. Analisis pembelauan sinar-X serbuk mendapati hasil sintesis yang diperolehi adalah SnSe dan CuInSe2 fasa tunggal. Serbuk yang telah disintesis digunakan sebagai bahan sumber untuk menyediakan filem nipis SnSe dan CuInSe2 meggunakan kaedah penyejatan dengan haba di dalam vakum. Kajian sifat struktur, komposisi, morfologi dan optik untuk filem yang dienapkan dijalankan dengan menggunakan pembelauan sinar-X (XRD), analisis penyerakan tenaga sinar-X (EDX), mikroskopi medan pancaran pengimbasan elektron (FESEM) dan spektroskopi UV-Vis-NIR. SnSe and CuInSe2 fasa tunggal dapat diperoleh tanpa melalui rawatan selanjutnya melalui kaedah penyejatan dengan haba di dalam vakum menggunakan sebatian SnSe dan CuInSe2 yang telah disintesis sebagai bahan sumber.
