Symposium T1 – Materials for Optoelectronics

Program Chairs: Lin Sun, Northwestern University; Jingshan S. Du, Northwestern University

Materials innovations have enabled new optoelectronic properties and applications ranging from photovoltaics, lasing, to light illumination. The fundamental understanding on the solid-state physics, quantum confinement phenomenon, and charge transfer mechanisms are critical in the design of emerging functional optoelectronic devices. In these explorations, conventional semiconductors usually suffer from limitations that are intrinsic to their materials properties. For instance, high sensitivity to impurities and poor mechanical properties challenges Si-based photovoltaics towards low- cost, flexible, and lightweight devices to be integrated into the holy grail of Internet of Things where each small device can be electrically powered. Therefore, the past decades have witnessed the emergence of novel photovoltaic materials addressing these challenges, such as organic photovoltaics, dye-sensitized solar cells, and more recently halide perovskites.

This symposium focuses on the discovery, design, and understanding of novel materials that have exotic optoelectronic properties. These include:

Plasmonics and photonics

  • Novel nanostructured materials
  • Basic understanding on wave-material interactions and scattering
  • Plasmonic and photonic materials for device integration

Opto-electronic conversion

  • Doping and crystal growth
  • Organic materials for photovoltaics and light emission
  • Lasing materials and structures
  • Materials for photodetection
  • Halide perovskites and other novel materials

Novel low-dimensional materials

  • Quantum well physics
  • Quantum dots
  • Nanowires and their applications
  • Novel 2D materials and van der Waals heterostructures

Symposium T2 – Materials Processing and Chemistry

Program Chair: Wenjie Zhou, Northwestern University

Recent advances of fabrication techniques in the field of nanophotonics shows great potential in replacing conventional components in many applications, such as lasing, and flat lenses. Strategies including bottom-up, or combinations of top-down and bottom-up are emerging as promising alternative of traditional lithography techniques, while bringing unprecedented features such as high precision, durability, and tunability. These alternative approaches could largely benefit the current nanofabrication platform, giving the nanophotonics community more opportunities to consider.

This symposium emphasizes the novel strategies to syntheses and processes of optically active materials. These include:

Top-down lithographic approaches

  • Optical lithography (UV, EUV)
  • Electron-beam lithography
  • Ion-beam lithography

Direct printing and writing approaches

  • Nano-imprint lithography
  • Nano-inject printing

Bottom-up assembly approaches

  • Template-assisted assembly
  • Interface-enabled assembly

Chemical processing and treatments

  • Wet chemical synthesis of materials
  • Surface processing and functionalization
