Talk Title: Nanoscale, Quantum, and Polarization Engineering of (Ultra)wide Bandgap Semiconductors for Next-Generation Microelectronics
Abstract: Wide and ultrawide bandgap semiconductors offer unprecedented opportunities to address some of the most critical challenges we face in the next decades: energy efficiency, clean energy, environmental sustainability, and quantum information. In this talk, I will present some recent advances of nanoscale, quantum, and polarization engineering of (ultra)wide bandgap semiconductors and their emerging applications in next-generation microelectronics, photonics, and clean energy. By exploiting the strong excitonic effect in extreme quantum-confined nanostructures, conventional low-efficiency AlGaN can be turned into high-brightness deep-ultraviolet emitters, which offer the only alternative technology to replace mercury lamps for water purification/disinfection. The strong excitonic effect can be further exploited to achieve ultrahigh efficiency nano-LEDs to power future virtual/augmented reality. I will also discuss how quantum, alloy, polarization, and facet engineering can transform conventional III-nitride semiconductors to be ferroelectric, with dramatically enhanced linear and nonlinear optical properties, piezoelectric response, photocatalytic functionality, and reconfigurability, that are urgently needed for integrated quantum photonics for information processing, acousto-electronics for 5G/6G technologies, high power and high temperature electronics, and light-driven artificial photosynthesis for clean energy.
