| dc.description | Today, the earnest need for low cost, earth-abundant, non-toxic, and environmentally friendly materials has revealed the importance of metal oxides (MOs) in order to eliminate the barrier towards their wide-ranging use in optoelectronic applications. MOs are the potential substitutes for metals, superconductors, semiconductors as well as insulators [1], [2]. Oxide semiconductors are extensively investigated in nascent applications, such as organic/inorganic solar cells, gas sensors, thin film transistors, as well as catalysts for hydrogen evolution [3], [4]. | |
| dc.description.abstract | In the present work, we demonstrate the growth of tin oxide (SnOx) thin films using electron beam evaporation method to study the phase transition from stannous oxide (SnO) to stannic oxide (SnO2) by varying annealing temperature (i.e., from 300 to 700 °C). Annealing induced morphology evolution and structural modifications stimulate the process of phase-transformation, which is primarily discussed by divided the entire temperature range into two-regimes. Regime-A (from 300 to 400 °C) consists of tetragonal α-SnO dominated phase, regime-B (from 600 to 700 °C) exhibits orthorhombic pure SnO2 phase. However, these regimes are being separated by an interface conferring a mixed-phase of tin oxides at an annealing temperature ∼500 °C. This temperature-dependent phase-inversion is adequately controlled by tuning the morphological, structural and optical properties of SnOx thin films to develop homo/heterostructures for various photovoltaic and optoelectronic applications.
