Extraterrestrial plasma crystals

01 Aug 2003

Some 10 years ago scientific interest in dusty plasmas was motivated mostly by the needs of the microelectronics industry. In 1994, however, researchers at three laboratories almost simultaneously found that these low-pressure gas discharges can organize themselves into crystal-like structures. This opened the door to spectacular developments in controlled crystal growth, such as the synthesis of thin films for solar-cell applications.

A plasma is typically a gaseous discharge containing electrons and positively charged ions. However,
