This new method uses a quartz shield to isolate the germanium that would otherwise be contaminated by the stainless steel chamber, insulation materials, or the graphite crucible. Doctors Mei and Wang also determined that use of a load scale can control the crystal diameter and ensure that all melted germanium is used in crystal production and thus removed...

Fluorinated ultra-thin film

Fluoropolymers have experienced widespread use as functional materials in applications ranging from water purification to energy storage. Production of large area, two-dimensional (2D), ultra-thin, semifluorinated polymer films is expected to have significant impacts on multiple fields. Some of these fields are organic electronics and optoelectronics...
