Congratulations to Dr. Jun Meng for winning the best poster award at the 2022 MRS fall meeting. The poster is entitled “Experimentally informed structure optimization of amorphous TiO2 films grown by atomic layer deposition ”. This work not only revealed the medium-range ordering in a-TiO2 thin film and provided a realistic a-TiO2 model for further structure-property studies, but also provided an improved StructOpt optimization package for efficient structure determination of complex materials guided by multiple inputs from experiments and simulations.
