There are fundamentally two ways to generate electricity. The first is based on electromagnetic induction, which remains the ...

Antimony selenosulfide (Sb2(S,Se)3) solar cells are emerging as a strong candidate for next-generation thin-film ...

Welsh rapers Goldie Lookin Chain (GLC) delivered a night of pure ‘chaos, beats, laughs’ - and tracks ‘your nan definitely wouldn’t approve of’ by the seaside in Tenby on Saturday night, at a bouncing ...

We report measurements of the valence band width in compressed Ge determined from x-ray emission spectra below the Ge K edge. The width of the valence band does not show any pressure dependence in the ...

Researchers in the Netherlands have investigated how carrier-selective contacts may help achieve stronger performance in back-contact (BC) crystalline silicon solar cells and have predicted ...

Conventional excitons are neutral composite particles formed when conducting electrons in solids bind with the holes they leave behind in the valence band. We predict the existence of a type of ...

The experimental results are consistent with the valence band model of hole-mediated ferromagnetism in the layers. The (Ga,Mn) (Bi,As) compound combines the properties of (Ga,Mn)As and Ga (Bi,As) ...

The impact of incorporating Bi into (Ga,Mn)As layers on their electronic, band structure, magnetic, and structural properties has been studied. The low-temperature molecular beam epitaxy technique was ...

The band's most well-remembered lead singer, Steve Perry, was spotted on a walk in Los Angeles earlier this month. The 74-year-old was the frontman and prominent songwriter for the band for 10 ...

An international research team has developed a new intermediate band solar cell (IBSC) design that includes a quantum ratchet (QR) semiconductor nanostructure. This new element reportedly enables ...
