Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at ...

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 ...

Researchers from Zhejiang University in China have investigated the impact of impurities and defects on the performance of solar cells built with mono cast silicon (CM-Si) wafers and have found that ...

“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 ...

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 ...

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 ...

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 ...

Using cutting-edge first-principles calculations, researchers at the University of California, Santa Barbara (UCSB) have demonstrated the mechanism by which transition metal impurities - iron in ...

Researchers led by Prof. ZHOU Wu from the University of Chinese Academy of Sciences (UCAS) and Prof. Sokrates T. Pantelides of Vanderbilt University have pushed the sensitivity of single-atom ...
