Nanostructured Oxide (SnO₂, FTO) Thin Films for Energy Harvesting: A Significant Increase in Thermoelectric Power at Low Temperature.

ABSTRACT: Previous studies have shown that undoped and doped SnO₂ thin films have better optical and electrical properties. This study aims to investigate the thermoelectric properties of two distinct semiconducting oxide thin films, namely SnO₂ and F-doped SnO₂ (FTO), by the nebulizer spray pyrolysis technique. An X-ray diffraction study reveals that the synthesized films exhibit a tetragonal structure with the (200) preferred orientation. The film structural quality increases from SnO₂ to FTO due to the substitution of F^- ions into the host lattice. The film thickness increases from 530 nm for SnO₂ to 650 nm for FTO films. Room-temperature electrical resistivity decreases from (8.96 ± 0.02) × 10^-2 Ω·cm to (4.64 ± 0.01) ×
