Cornell researchers have developed a new transistor architecture that could reshape how high-power wireless electronics are engineered, while also addressing supply chain vulnerabilities for a critical semiconductor material.

A custom-built, metal-organic chemical vapor deposition system in Duffield Hall will help forge new directions for nitride semiconductors, materials best known for enabling LEDs and 5G communications.

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors – technology that could potentially be used for classical and quantum communications networks.

Cornell researchers have demonstrated that, by zapping a thin film with ultrafast pulses of low-frequency infrared light, they can cause its lattice to atomically expand and contract billions of times per second, potentially switching its electronic, magnetic or optical properties on and off.

A new innovation from Cornell researchers lowers the energy use needed to power artificial intelligence – a step toward shrinking the carbon footprints of data centers and AI infrastructure.

Cornell University hosted the 2025 SUPREME annual review, bringing together academia, industry, and government to advance next-generation semiconductor innovation and workforce development.
