Nb doped SrTiO3 thin films deposited by pulsed laser ablation

Physical aspects of ferroelectric semiconductors for photovoltaic solar energy conversion

“…This will ensure epitaxial growth of the overall heterostructure with high crystal, interface quality and low defect densities. The most promising candidates, including NiO x (Sato et al, 1993), MoO 3 (Hamwi et al, 2009), indium doped SrTiO 3 (Huang et al, 2016), and niobium doped SrTiO 3 (Fukushima and Shibagaki, 1998), magnesium or aluminum doped ZnO (Karger and Schilling, 2005), as p-and n-type materials respectively are given in Fig. 37(a).…”

Effect of oxygen vacancy distribution on the thermoelectric properties of La-doped SrTiO3 epitaxial thin films

“…Annealing in Ar/H 2 creates more oxygen vacancies in film A, leading to an enhanced Coulomb repulsion of cations, which results in an increase in lattice parameter. 35 The crystallite size of the films is calculated to be $50 nm, using the Scherrer formula and is found to be independent of annealing.…”

Oxygen Sensing Properties of SrTiO3 Thin Films

“…The electrical conductivities of SrTiO 3 can be easily controlled by selecting doping donors, such as Nb, [4][5][6][7][8][9][10][11][12][13][14][15][16][17] even in thin film form without any impurity phases. [5][6][7]17) From the viewpoint of conductivity, SrTiO 3 can be changed from an insulator to an n-type semiconductor, and finally to a metallic conductor; in cryogenic temperatures, it can even be changed to a superconductor. 9) It is very important to control conductivity for SrTiO 3 to achieve various electronic applications.…”
