April Flowers for redOrbit.com - Your Universe Online A new form of very hard carbon clusters capable of indenting diamond has been observed by a team of Carnegie Institution for Science researchers. The carbon clusters are unusual in their mix of crystalline and disordered structures and have potential applications for a range of mechanical, electronic, and electrochemical uses. The team, led by Lin Wang, published their findings in the August 17, 2012, issue of Science. Carbon...

An amorphous diamond — one that lacks the crystalline structure of diamond, but is every bit as hard — has been created by a Stanford-led team of researchers. But what good is an amorphous diamond? "Sometimes amorphous forms of a material can have advantages over crystalline forms," said Yu Lin, a Stanford graduate student involved in the research. The biggest drawback with using diamond for purposes other than jewelry is that even though it is the hardest material known,...

SAN JOSE, Calif., Nov. 24 /PRNewswire-FirstCall/ -- Novellus Systems (Nasdaq: NVLS) has developed a suite of ashable hardmask (AHM) films that have up to 25 percent greater etch selectivity compared to similar amorphous carbon films in use by the industry today. This highly selective and transparent (HST) AHM family of films has demonstrated die yield improvements as much as 7 percent when coupled with Novellus' patented integrated edge bevel removal (EBR) technology.

A great deal of work has been done into understanding the physical properties of amorphous carbon (a-C). These studies have found the relative ratio of different carbon phases strongly determines the physical properties of the material. In this work, published in AZojomo*, by B. Rebollo-Plata, R. Lozada-Morales, R. Palomino-Merino, J. A. Dávila-PintLe, O. Portillo-Moreno, O. Zelaya-Angel and S. Jim©nez-Sandoval from Benem©rita Universidad Aut³noma de Puebla, a-C thin...
