Symposium EL02-Fundamentals of Halide Semiconductors for Optoelectronics

For the last decade, metal halide semiconductors have successfully demonstrated their significant capability for optoelectronic applications. Recently, metal halide semiconductors have emerged as a new class of light emitters as well as various photodetectors. Their superior optical and electronic properties and the bandgap tunability suggest that they will be useful in various optoelectronic applications. Solution processability of halide semiconductors makes these materials especially attractive for low-cost and scalable manufacturing of next-generation optoelectronic devices.

On the other hand, there is still a lack of fundamental understandings in physics, chemistry, and materials science of these new halide optoelectronic materials. This symposium will focus on a wide range of metal halide semiconductors including lead-based halide emitters, low-dimensional halide semiconductors, and non-toxic heavy-metal-free halide semiconductors to explore the fundamentals of those halide materials, including theoretical calculation, crystal/defect chemistry, carrier dynamics, photophysics, and ion migration. This symposium will also cover their use in various optoelectronic devices including light-emitting diodes, visible and infrared photodetectors, radioactive detectors, and lasers.

Topics will include:

  • Theoretical calculation and simulation on halide semiconductors
  • Synthesis and crystal/defect chemistry of halide semiconductors
  • Lead-based halide emitters
  • Low-dimensional (0D, 1D, 2D) halide semiconductors
  • Non-toxic heavy-metal-free halide semiconductors
  • Carrier dynamics and transportation mechanisms
  • Photophysics (excitation, recombination, PL, EL) of halide semiconductors
  • New device architecture in halide LEDs
  • Halide semiconductor lasers
  • Detectors (photodetectors and radioactive detectors)
  • Other optoelectronic devices
  • A tutorial complementing this symposium is tentatively planned.
