DESCRIPTION:Control of symmetry breaking in organic-inorganic hybrid semic
 onductors\n\nOrganic–inorganic hybrid semiconductors provide a versatile 
 platform in which the structural tunability of molecular components can b
 e coupled with the exceptional electronic and optical properties of an in
 organic lattice. A particularly powerful aspect of these materials is the
  ability to manipulate symmetry breaking across multiple length and time 
 scales\, creating new opportunities to control light–matter interactions\
 , spin dynamics\, and functional excited states.\n\nIn this seminar\, I w
 ill discuss our efforts to understand and control symmetry breaking in me
 tal halide hybrid semiconductors through molecular design\, compositional
  engineering\, and light–matter interactions. First\, I will describe how
  optical excitation can drive hybrid metal halides into long-lived\, meta
 stable polar states\, revealing a pathway to dynamically generate broken-
 symmetry structures that are inaccessible under equilibrium conditions. T
 he coupling between photoexcitation\, lattice distortion\, and structural
  dynamics provides new opportunities for controlling nonlinear optical re
 sponses and persistent material functionalities.\n\nI will then discuss h
 ow chiral organic–inorganic perovskites provide a molecular approach to c
 ontrolling inversion symmetry and spin-dependent photophysics. Using ultr
 afast\, spin-resolved spectroscopy\, we investigate how structural chiral
 ity and spin–orbit coupling govern carrier spin polarization and relax\n\
