A Deep Etching Mechanism for Trench-Bridging Silicon Nanowires

Introducing a single silicon nanowire with a known orientation and dimensions to a specific layout location constitutes a major challenge. The challenge becomes even more formidable, if one chooses to realize the task in a monolithic fashion with an extrem ...

Piezoelectric AlScN thin films: A semiconductor compatible solution for mechanical energy harvesting and sensors

Paul Muralt, Ramin Matloub Aghdam, Silviu Cosmin Sandu, Andrea Mazzalai, Mahmoud Hadad, Nachiappan Chidambaram

The transverse piezoelectric coefficient e31,f of Al1-xScxN thin films was investigated as a function of composition. It increased nearly 50% from x = 0 to x = 0.17. As the increase of the dielectric constant was only moderate, these films are very suitabl ...
