Point defects are one of the most common and important structural disorders in crystalline materials. Although they are usually regarded as unwanted and unavoidable defects that cause material failure ...

Strain- and defect-engineering are two powerful approaches to tailor the opto-electronic properties of two-dimensional (2D) materials, but the relationship between applied mechanical strain and ...

Materials scientists have long known that introducing defects into three-dimensional materials can improve their mechanical and electronic properties. Now a new Northwestern study finds how defects ...

Material optimization: Strain can be applied to overcome doping limitations in semiconductors. (Courtesy: B Huang) A new universal theory and three basic rules for how defects in semiconductors behave ...

A Chinese research team has investigated impurity and defect levels in solar cells based on mono cast wafers and have found that around 30% of the devices present an “excessive” reduction in power ...

“Traps” are places where an electron can be found "trapped" within a semiconductor. These traps are highly undesirable because they prevent electrons from moving around quickly so that they can be ...

The semiconductor industry and pretty much all of electronics today are dominated by silicon. In transistors, computer chips, and solar cells, silicon has been a standard component for decades. But ...

Semiconductors may be small, but the impacts they have are significant. Semiconductors used in life-dependent applications, such as pacemakers, defibrillators, life support systems, automotive safety ...

Metrology is the science of measuring, characterizing, and analyzing materials. Within metrology, there are several technologies used to detect material defects on a very small scale – precision on ...

The emergence of new materials has opened the doors to nano-electronic and optoelectronic devices with new or improved capabilities. For example, III-V based alloys have transformed the LED industry ...
