The influence of the transparent conducting oxide (TCO) topography was studied on the performance of a silicon oxide intermediate reflector layer (IRL) in a-Si/μc-Si tandem cells, both experimentally and by 3-D optical simulations. Therefore, cells

LiMo(3)Se(3) is a highly anisotropic solid comprised of a regular pattern of quasi-1-D wire-like structures. Solutions of LiMo(3)Se(3) deposited on substrates and TEM grids reveal the presence of two-dimensional network morphologies. High resolution

We report a model of nanowire (NW) mechanics that describes force vs displacement curves over the entire elastic range for diverse wire systems. Due to the clamped-wire measurement configuration, the force response in the linear elastic regime can be

To exploit the novel size-dependent mechanical properties of nanowires, it is necessary for one to develop strategies to control the strength and toughness of these materials. Here, we report on the mechanical properties of silver nanowires with a un

Surface texturing in thin-film solar cells provides a promising way of addressing the loss components due to reflection and poor light absorption inside the cells. In this work, we study the reflection suppression performance of different submicron-s

The direct depth measurement of structures with aspect ratios between 1 and 4 in the arrays of memory cells represents a major challenge for inline metrology. For 75 nm and larger technology nodes these measurements are carried out using inline AFM u
