摘要：
Tin-doped gallium oxide (Ga2O3:Sn) films have been deposited on single crystalline MgO (100) substrates by metal organic chemical vapor deposition technique. The tin content was varied from 5 to 20 % (atomic ratio). After annealing in the atmosphere, all the samples show the beta phase with the epitaxial relationship of beta-Ga2O3 () ayen MgO (100). The average transmittance for the annealed samples in visible range exceeds 89 %. The resistivity of the films doped with Sn can be effectively decreased by almost five orders of magnitude. A narrow and strong violet photoluminescence from 390 to 430 nm is observed at room temperature and this violet emission is enhanced after Sn-doping.
