Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Avalanche photodiodes (APDs) for ultra-sensitive infrared detection at eye-safe wavelengths are built around compound ...

Product security and reliability are major concerns in the semiconductor and PCB fabrication industries. Because of this, ...

Off-the-board technology has proceeded in three waves, and the third wave is still unfolding. Based on the author’s experience working with startups, the third wave may coincide with the end of copper ...

Experiments show that carbon nanotubes transfer heat inefficiently at small scales, raising concerns for cooling and ...

In this paper, the effect of junction temperature swing duration on lifetime of transfer molded power insulated gate bipolar transistor (IGBT) modules is studied and a relevant lifetime factor is ...

The hot-spot temperature and the current shared by the core were calculated by using the measured voltages. The impact of the current sharing on the reduction of hot-spot temperature is discussed.

Surface melting on the Greenland Ice Sheet is on a slightly above-average track for the 2025 melt season, with melt along the western coast leading the way. Overall, total melt-day extent as of June ...
