Today’s Spotlight uses a series of images by Winston Chern and James Teherani showing a micrograph of an experimental transistor, blue highlighting indicates areas of "strain," where germanium atoms have been forced closer together than they find comfortable. Black represents zero strain.
Almost all computer chips use two types of transistors: one called p‑type, for positive, and one called n‑type, for negative. Improving the performance of the chip as a whole requires parallel improvements in both types.
At the IEEE’s International Electron Devices Meeting (IEDM) in December, researchers from MIT’s Microsystems Technology Laboratories (MTL) presented a p‑type transistor with the highest “carrier mobility” yet measured. By that standard, the device is twice as fast as previous experimental p‑type transistors and almost four times as fast as the best commercial p‑type transistors.
