Texture‐Enhanced Mechanical Stability of Transparent Electrodes for Flexible Optoelectronics with Near‐Infrared Response

open access: yesAdvanced Materials Interfaces, EarlyView.
Texturing of indium tin oxide (ITO) electrodes on plastic substrates is found to enable both, a remarkable transparency up to the near‐infrared region, and a massively enhanced mechanical stability upon bending. Therefore, textured ITO electrodes are an appealing option for flexible opto‐electronic applications with near‐infrared response, such as all ...

FCC-ee: Energy Calibration

open access: yes, 2015
FCC-ee aims to improve on electroweak precision measurements, with goals of 100 keV on the Z mass and width, and a fraction of an MeV on the W mass. Compared to LEP, this implies a much improved knowledge of the centre-of-mass energy when operating at the Z peak and WW threshold.
