Transition metals have long been used as catalysts to activate small molecules and turn them into valuable products. However, as these metals can be expensive and less abundant, scientists are ...

In contrast, p-type silicon is silicon doped with boron gas that turns it into a conductive material that readily accepts electrons when voltage is applied. Boron has only three electrons in its ...

[Zachary Tong] is dipping his toes into the DIY semiconductor world, and further to the goal of keeping costs to a hobbyist scale, is experimenting with laser doping of silicon. Doping is the ...

So manufacturers beef up or "dope" the cell's two silicon layers with trace amounts of additives, typically phosphorus and boron. The top, phosphorus-doped layer contains more electrons ...

Their results are published in Nature Communications. The researchers found that boron-doped diamonds exhibit plasmons—waves of electrons that move when light hits them—allowing electric ...

In addition, boron-doped Cz-Si and boron-doped float zone silicon (FZ-Si) wafers were investigated for comparison. “Our experiments on lifetime samples confirm that LeTID can, in fact occur in ...

The holes are formed because Group III elements have one less electron than silicon. PERC technologies on p-type substrates currently enjoy a dominant position among PV manufacturers. Boron-doped ...

Making it into working circuits requires dopants like phosphorous and boron to give the silicon the proper semiconductor properties. But even then, a doped wafer doesn’t do much until an ...

The modified material was then exposed to flowing ammonia at 1000 °C, which resulted in sodium-doped amorphous silicon-boron-nitride (Na-doped SiBN). Using cutting-edge spectroscopic techniques ...

known as boron-doped diamonds. Their findings could pave the way for new types of biomedical and quantum optical devices—faster, more efficient, and capable of processing information in ways that ...
