Growth of Cu2ZnSnS4 absorber layer on flexible metallic substrates for thin film solar cell applications
In this work, Cu2ZnSnS4 (CZTS) absorber layers were fabricated using a two-stage process. Sequentially deposited Cu-Zn-Sn thin film layers on metallic foils were annealed in an Ar + S2(g) atmosphere. We aimed to investigate ...
Improvement of optical and electrical properties of ITO thin films by electro-annealing
The effect of electro-annealing in vacuum and air on the optical and electrical properties of ITO thin films grown by large area DC magnetron sputtering was investigated. Moreover, the performances of the electro-annealed ...
Area dependence and influence of crystal inhomogeneity on superconducting properties of Bi2212 mesa structures
The rapid increase in applications of terahertz waves requires new techniques to obtain continuous wave terahertz sources. Mesa structures fabricated from high-Tc superconductor Bi2Sr2CaCu2O8+δ (Bi2212) single crystal have ...
Interferometer measurements of terahertz waves from Bi 2Sr 2CaCu 2O 8+d mesas
(IOP Publishing, 2012-12)
We fabricated rectangular mesa structures of superconducting Bi 2Sr 2CaCu 2O 8+d (Bi2212) using e-beam lithography and Ar ion beam etching techniques for terahertz (THz) emission. c-axis resistance versus temperature (R-T), ...
