Excitonic Wave

The following provides a brief overview of major conferences and technical meetings to be held in the United States during Fall 2026 that are relevant to exciton physics, two-dimensional (2D) semiconductors, optoelectronics, quantum materials, nanophotonics, and advanced semiconductor devices.

The conferences are organized chronologically by month. Among the meetings reviewed, the MRS Fall Meeting is considered particularly relevant to research on excitons and 2D semiconductor materials. In comparison, IEDM, AVS, and SEMICON West offer stronger coverage of advanced semiconductor devices, materials processing, device integration, manufacturing, and industrial applications. Collectively, these conferences provide a broad perspective spanning fundamental exciton physics and materials research to semiconductor device development and emerging technology applications.

Frontiers in Optics + Laser Science 2026 (FiO LS)
September 27 – October 1 | Rochester, New York

FiO LS focuses on optics, photonics, laser science, and light–matter interactions. It is relevant to exciton research through topics such as optical spectroscopy, ultrafast exciton dynamics, nanophotonics, quantum optics, and exciton–photon coupling.

Relevance: ★★★★☆

SEMICON West 2026
October 13–15 | San Francisco, California

SEMICON West is a major U.S. event for the semiconductor industry, covering advanced semiconductor manufacturing, materials, packaging, photonics, and emerging technologies. It is particularly useful for understanding the transition from advanced semiconductor materials and optoelectronic concepts toward manufacturing, integration, and commercialization.

Relevance: ★★★☆☆
Industry & commercialization relevance: ★★★★★

AVS 72nd International Symposium & Exhibition
November 8–13 | Pittsburgh, Pennsylvania

AVS covers materials, surfaces and interfaces, thin films, semiconductor processing, nanoscale science, and quantum technologies. Its 2D materials and electronic materials sessions are particularly relevant to 2D semiconductor growth, interfaces, defects, characterization, and device integration.

Relevance: ★★★★☆

IEEE Photonics Conference (IPC) 2026
November 8–12 | Denver, Colorado

The IEEE Photonics Conference focuses on photonics, optoelectronics, semiconductor lasers, integrated photonics, and emerging optical technologies. It is relevant to exciton-based semiconductor research when the focus is on light–matter interaction, optical properties, quantum photonics, and semiconductor-based photonic devices.

Relevance: ★★★★☆

MRS Fall Meeting & Exhibit 2026 — Highly Recommended
November 29 – December 4 | Boston, Massachusetts

The MRS Fall Meeting is arguably the most directly relevant major U.S. conference for exciton and 2D semiconductor research.

Key topics include:

Overall, MRS provides a strong connection between fundamental exciton physics, 2D materials, optical phenomena, and next-generation semiconductor devices.

Relevance: ★★★★★
Priority: ⭐⭐⭐⭐⭐

IEEE International Electron Devices Meeting (IEDM) 2026
December 12–16 | San Francisco, California

IEDM is one of the world's leading conferences on advanced semiconductor devices and emerging device technologies. It is especially relevant when exciton-related research moves toward device architectures, novel semiconductor materials, quantum/emerging devices, optoelectronics, and heterogeneous integration.

While IEDM is less focused on fundamental exciton physics than MRS, it offers an important perspective on how emerging semiconductor phenomena can be translated into practical device technologies.

Relevance: ★★★★☆
Advanced device & industry relevance: ★★★★★

For research focused specifically on exciton–semiconductor technology, the following conferences are prioritized based on their relevance to the field:

In particular, MRS Fall Meeting 2026 in Boston should be considered a top priority because its program directly addresses excitons in 2D semiconductors, exciton transport, TMDs, moiré systems, perovskites, and optoelectronic devices.

This overview is intended to provide a reference for strategic planning of conference participation, research presentations, and potential collaborative opportunities during Fall 2026.
