Modulated surface texturing on temporary aluminium substrate for flexible thin-film solar cells

Thin-film photovoltaic technologies are gaining momentum over the currently dominated crystalline silicon technologies. In addition to the competitive prices, flexible thin-film technology especially has the added advantage such as in building integrated photovoltaics (BIPV) due to its flexibility and light weight. HyET Solar B.V. is a company...

A 3D microelectrode array to record neural activity at different tissue depths

Measuring neuronal responses along all three spatial dimensions is the next step, beyond the capacity of established 2D microelectrode arrays (MEAs), to record electric activity inside tissues with highly accurate spatial resolution. This research presents silicon-based planar arrays of 3D microelectrodes, whereby each microelectrode supports...

A transfer-free wafer-scale CVD graphene fabrication process for MEMS/NEMS sensors

In this paper we report a novel transfer-free graphene fabrication process, which does not damage the graphene layer. Uniform graphene layers on 4" silicon wafers were deposited by chemical vapor deposition using the CMOS compatible Mo catalyst. Removal of the Mo layer after graphene deposition results in a transfer-free and controlled placement...
