Abstract:
We investigate the effect of dopant species and structure on the thermal conductivity of Sb-doped SnO 2 (ATO) and Ta-doped SnO 2 (TTO) films and compare the results with those of In 2 O 3 -, ZnO-, and TiO 2 -based transparent conductive films. The thermal conductivities (λ) of polycrystalline ATO and TTO films are 4.4–4.9 and 4.7 W m −1 K −1 , respectively. The thermal conductivities via phonons (λ ph ) are almost identical for both dopant species (Sb and Ta): 4.3 and 4.5 W m −1 K −1 for Sb and Ta, respectively, on average. These results for λ ph are larger than that for Sn-doped In 2 O 3 films (3.8 W m −1 K −1 ) and considerably larger than that for amorphous ATO films (1.0 W m −1 K −1 ). These facts lead us to conclude that the base-material species (SnO 2 or In 2 O 3 ) and structure (polycrystalline or amorphous) affect the thermophysical properties of ATO and TTO much more than the dopant species.
