In biology, defects are generally bad. But in materials science, defects can be intentionally tuned to give materials useful new properties. Today, atomic-scale defects are carefully introduced during ...

A new model measures defects that can be leveraged to improve materials' mechanical strength, heat transfer, and ...

(A) The crystal structure of GeTe co-doped with Sb and Ni, illustrating the dual mechanism of facilitating carrier transport (purple arrows) while effectively scattering phonons (red waves). (B) ...

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 ...

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 ...

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 ...

A technical paper titled “Accelerating Defect Predictions in Semiconductors Using Graph Neural Networks” was published by researchers at Purdue University, Indian Institute of Technology (IIT) Madras, ...

Perovskite solar cells have been the subject of much research as the next generation of photovoltaic devices. However, many challenges remain to be overcome for the practical application. One of them ...
