Description:About the seminar:\n\nPerovskites\, ABX3\, have been identified
  as next-generation semiconducting and photovoltaic materials from hybrid 
 halide perovskites reaching commercialization. One subset of perovskites t
 hat has been historically understudied are sulfur and chalcogenide contain
 ing perovskites. Owing to a change in electronegativity from classical hal
 ides or oxygen on the X-sites\, these perovskites have softer\, more polar
 izable bonds. This results in more applicable properties for semiconductin
 g applications such as smaller bad gaps\, increased electronic conductivit
 y\, and increased thermal stability. In part\, the difficult synthesis con
 ditions of long times and extremely hot temperatures have limited the disc
 overy of new Sulfur/chalcogenide based perovskites. This seminar will intr
 oduce a work showcasing a newly discovered reaction pathway to synthesize 
 the chalcogenide perovskite\, BaZrS3\, featuring lower temperate growth me
 chanisms\, higher precursor reactivity\, and halide catalysts that improve
  upon current literature synthesis for this class of material making new m
 aterials discovery more accessible. 4:00 pm
