Fitting Terahertz Waves onto a Single Chip: How UCLA Broke a 30-Year Barrier by Repurposing Quantum Wells
Terahertz waves are valuable for imaging and high-speed communication, but the sheer size and cost of equipment have long blocked widespread adoption. A UCLA research team has developed a technology that repurposes quantum well structures—a standard building block in optical communications—to integrate the core functions onto a single chip, opening the door to dramatic system miniaturization and mass production.

The Thinner It Gets, the Better It Conducts: Researchers Develop NbAs Nanowires to Replace Copper Interconnects
As semiconductor wiring shrinks, copper's electrical resistance surges toward a physical limit. In response, a Cornell University research team has developed a new technology using the topological semimetal niobium arsenide. This material has the unusual property of becoming more conductive as the wire gets thinner, potentially contributing to performance gains in next-generation chips.
