Research & Innovation


Semiconductor Wafer Inc. can provide both single crystal SrTiO3 wafer and conductive Nb doped SrTiO3 wafer with size from 5 x 5 mm to diameter 25 mm . With excellent physical and mechanical properties , SrTiO3 has twin free crystal structure and it's lattice contant can perfectly match to the common superconductor materials . Pure SrTiO3 substrate is the best choice for your high Tc superconductor application , conductive SrTiO3 wafer can be as an electrode for certain thin film / device applications , single crystal SrTiO3 can exhibit electric conductive by doping Nb ( Niobium ) , different doped concentration ( 0.1 ~ 1 wt% ) will change resistivity range from 0.001 to 0.1 ohm-cm , and this will be of benefit to some thin film application . Please contact us for more product information .
