02-2020-IMT PhD Position on Cooperative Actuator Systems for Nanomechanics and Nanophotonics
So far, the vast majority of actuators for nanomechanical / nanophotonic switching and tuning is based on electrostatics, using either comb-drive or gap closing actuators. These actuators have in common that they require a large footprint exceeding 100 x 100 µm² in many cases, which results from limited effect size due to poor down-scaling. These limitations may be overcome by introducing novel nanoactuators based on shape memory alloy (SMA) films. SMA films exhibit highest work den-sities up to 107 Jm-3 and favorable down-scaling of actuation performance. Recently, an ultra-compact nanophotonic switch has been demonstrated having a footprint of only 1 x 1 µm².
The PhD thesis aims at the development and experimental investigation of novel bistable and multi-stable SMA-polymer actuator systems and their combination with silicon nano-technology for switch-ing and tuning of nanometer-scale silicon devices. A monolithic fabrication technology is required to achieve a high integration density. For micro/nano fabrication, the IMT operates a state-of-the-art clean room facility. In addition, advanced simulation tools and measurement equipment are available. The PhD thesis includes the following tasks:
• Characterization of material properties (structure, mechanical, thermal, magnetic)
• Micro- and nanofabrication technologies (optical and electron beam lithography, RIE)
• Modelling, design and simulation (FEM multiphysics, lumped element modelling)
• Characterization of demonstrator variants in a SEM (mechanical, optical, electrical properties)
We are looking for ambitious, creative and self-motivated individuals, who like to work within an inter-disciplinary and international team. Your background covers one or several of the following topics: Micro/nano technologies, mechanical and electrical engineering, materials science. Experience in CAD, FEM simulation and MATLAB programming are of advantage.
