Laser enhancement - A path to defect free diamond growth?

by Shannon Nicley Demlow in Blingtronics - Science, Engineering and Diamonds

In this post I'll take a look at an article titled "Control of crystallographic orientation in diamond synthesis through laser resonant vibrational excitation of precursor molecules" published recently in Scientific Reports. In the article, Zhi Qiang Xie and coworkers describe the potential benefits of using a laser to introduce resonant vibrations of molecules during the growth of diamond films. How can laser light improve the growth process, and does this technique hold promise for improving diamond growth in general?... Read more »
