  • Building electronics that don’t die: Columbia's breakthrough at CERN
    Deep beneath the Swiss-French border, the Large Hadron Collider unleashes staggering amounts of energy and radiation—enough to fry most electronics. Enter a team of Columbia engineers, who built ultra-rugged, radiation-resistant chips that now play a pivotal role in capturing data from subatomic particle collisions. These custom-designed ADCs not only survive the hostile environment inside CERN […]
  • Digital twins are reinventing clean energy — but there’s a catch
    Researchers are exploring AI-powered digital twins as a game-changing tool to accelerate the clean energy transition. These digital models simulate and optimize real-world energy systems like wind, solar, geothermal, hydro, and biomass. But while they hold immense promise for improving efficiency and sustainability, the technology is still riddled with challenges—from environmental variability and degraded equipment […]
  • Quantum tunneling mystery solved after 100 years—and it involves a surprise collision
    For the first time ever, scientists have watched electrons perform a bizarre quantum feat: tunneling through atomic barriers by not just slipping through, but doubling back and slamming into the nucleus mid-tunnel. This surprising finding, led by POSTECH and Max Planck physicists, redefines our understanding of quantum tunneling—a process that powers everything from the sun […]
  • Decades of chemistry rewritten: A textbook reaction just flipped
    Penn State researchers have uncovered a surprising twist in a foundational chemical reaction known as oxidative addition. Typically believed to involve transition metals donating electrons to organic compounds, the team discovered an alternate path—one in which electrons instead move from the organic molecule to the metal. This reversal, demonstrated using platinum and palladium exposed to […]
  • You’ve never seen atoms like this before: A hidden motion revealed
    A pioneering team at the University of Maryland has captured the first-ever images of atomic thermal vibrations, unlocking an unseen world of motion within two-dimensional materials. Their innovative electron ptychography technique revealed elusive “moiré phasons,” a long-theorized phenomenon that governs heat, electronic behavior, and structural order at the atomic level. This discovery not only confirms […]
  • This Algorithm Just Solved One of Physics’ Most Infamous Problems
    Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and solve the long-standing polaron problem, unlocking deeper understanding of electron flow in tricky materials.

Scaling of CMOS and its Issues

Dennard scaling revolutionized microelectronics by showing that reducing transistor size and voltage proportionally keeps power density constant. However, real-world limitations like subthreshold slope and interconnect resistance eventually halted its ideal progression, demanding alternative approaches to maintain performance improvements in modern technology nodes.
