Novel Family of Semiconductors


New research paper titled "Semiconducting silicon–phosphorus frameworks for caging exotic polycations" from researchers at Department of Chemistry, Iowa State University, and Ames Laboratory, U.S. Department of Energy. Abstract "A series of novel semiconductors AAe6Si12P20X (A = Na, K, Rb, Cs; Ae = Sr, Ba; X = Cl, Br, I) is reported. Their crystal structures feature a tetrahedral Si–P f... » read more

Week In Review: Manufacturing, Test


Worldwide fab equipment spending for front-end manufacturing is expected to hit $107 billion this year, an 18% year-over-year increase, according to SEMI’s latest World Fab Forecast report. “Crossing the $100 billion mark in spending on global fab equipment for the first time is a historic milestone for the semiconductor industry,” said Ajit Manocha, president and CEO of SEMI.

Manufacturing Bits: Dec. 6


China’s rare earth power play Rare earth elements (REEs) are back in the news. China, the world’s largest supplier of rare earths, plans to combine three domestic vendors to create a large state-owned company with a nearly 70% share of the REE market, according to reports from Nikkei and others. In 2020, China in total accounted for 85% of global production of refined REEs, accordi... » read more

Hedgehog spin-vortex crystals The U.S. Department of Energy’s Ames Laboratory has discovered a missing piece to enable novel superconductor devices--the hedgehog spin-vortex crystal phase. Superconductors are devices that have zero electrical resistance, making them attractive for a range of applications. But superconductors must be cooled down to temperatures at or near absolute zero on ... » read more

Diamond metrology The U.S. Department of Energy’s Ames Laboratory is building a new instrument called an optical magnetometer. The system will help researchers understand the properties of new magnetic nanomaterials. The system, dubbed the NV-magnetoscope, makes use of the properties of nitrogen-vacancy (NV) centers in diamonds. According to researchers, diamonds have a flaw, or imperfect... » read more
