Gallox Semiconductors Inc.

Gallox Semiconductors Inc., a for-profit manufacturer based in Ithaca, New York, develops gallium oxide power semiconductor devices for federal customers as a prime contractor and sub-recipient on early-stage research grants. The vendor operates under the Total Small Business set-aside on its sole contract work and competes on Small Business Technology Transfer (STTR) grants from the National Science Foundation.

Gallox's federal footprint is nascent and highly concentrated in advanced materials research. The vendor has received three total awards across two distinct customer agencies — the National Science Foundation (one STTR Phase I grant) and the Department of the Air Force (one purchase order and one sub-award from Cornell University). The Air Force Research Laboratory issued a $139,726 firm-fixed-price purchase order on March 13, 2026, for field management of high-voltage gallium oxide devices, with work performed in Ithaca and an ultimate completion date of September 13, 2026. The NSF Technology, Innovation, and Partnerships program (CFDA 47.084) funded a $305,000 STTR Phase I project grant running from February 1, 2025, to January 31, 2026, to evaluate gallium oxide power devices in data-center power converters and improve power-conversion efficiency. Under that NSF grant, Gallox serves as a sub-recipient of a Cornell University prime award (dated March 24, 2025), developing patent-pending thermal management solutions for gallium oxide devices while Cornell focuses on in-situ etch process development to reduce contact resistance.

Activity is minimal and recent — two awards in 2025 and one in 2026. One award (the Air Force purchase order, $140 thousand combined potential value) reaches completion within the next twenty-four months and faces recompete exposure. Combined obligated dollars ($535 thousand) exceed combined potential value by 383 percent, indicating front-loaded funding or multiple task or funding actions against the same vehicle.
