Abstract: Nanomaterials often show very different sizes, shapes, and stability properties. They also facilitate electron transfer and can be easily modified with chemical ligands and biomolecules. These properties, combined with the ease of miniaturizing nanoscales and their application to sensing devices, make nanoma…

The effect of strain on the phonon modes of monolayer and few-layer MoS${}_{2}$ has been investigated by observing the strain-induced shifts of the Raman-active modes. Uniaxial strain was applied to a sample of thin-layer MoS${}_{2}$ sandwiched between two layers of optically transparent polymer. The resulting band sh…

Thin-film crystalline silicon (c-Si) solar cells with light-trapping structures can enhance light absorption within the semiconductor absorber layer and reduce material usage. Here we demonstrate that an inverted nanopyramid light-trapping scheme for c-Si thin films, fabricated at wafer scale via a low-cost wet etchin…

The current–voltage (I–V) characteristics of CrNiCo alloy Schottky contacts on a molecular-beam epitaxy n-GaAs substrate have been measured over the temperature range of 130–330 K and have been interpreted based on the assumption of a Gaussian distribution of barrier heights due to barrier height inhomogeneities that…

The authors investigate the influence of strain on the electronic properties of monolayer WSe${}_{2}$ using optical absorption and photoluminescence spectroscopy. The linewidth of the $A$ exciton exhibits a significant and unexpected decrease, from 42 to 24 meV at room temperature. A slightly different behavior is obs…

Only ten micrometer thick crystalline silicon solar cells deliver a short-circuit current of 34.5 mA cm(-2) and power conversion efficiency of 15.7%. The record performance for a crystalline silicon solar cell of such thinness is enabled by an advanced light-trapping design incorporating a 2D inverted pyramid photonic…
