Tunnelling devices based on semiconductor heterojunctions offer the potential for computation with very high energy efficiency. This potential exists because…
Semiconducting alloys of InxGa1-xAs, GaAsySb1-y, and InAszP1-z can be fabricated to exhibit band gaps between 0.5 and 1.0 eV, which…
Yellow-green LEDs with emission at the wavelengths of 570-580 nm are commercially interesting because they can be combined with blue…
Photovoltaics and sustainability have received much attention lately. We seek a tandem photovoltaic device using silicon as both the substrate…
