Atomic Force Microscopy (AFM) has evolved into a useful tool for nanoscale imaging of surfaces with high resolution in many technical and scientific application areas. Major efforts are invested into quantitative measurement of nano-mechanical properties of samples. However, these measurements typically rely on nanoindentation techniques where the large contact force during snap into contact can cause irreversible damage to the tip and the sample. This poses a big challenge in proper mechanical characterization of ultra-thin membranes where such damages could rupture the membrane and yield unreliable measurements.
As a postdoc you will be working on developing new techniques for accurately probing tip-sample interactions utilizing nonlinear dynamic response of AFM in contact with hard as well as soft suspended nanomaterials.
Your tasks will involve:
- Developing, conducting and supervising research on nonlinear dynamics at the nanoscale with focus on atomic force microscopy and atomically thin membranes.
- Performing experiments for probing nonlinear nanoscale forces between AFM and suspended atomically thin membranes.
- Developing a nonlinear identification technique for estimating sample properties in dynamic mode AFM using tip-sample interaction nonlinearities.
- Engaging in the writing of scientific articles and proposals to secure funding for further work on the topic.
Applicants must have the following qualifications:
- PhD in Mechanical Engineering, Electrical Engineering , Physics or Mathematics.
- Solid background in either nonlinear dynamics or atomic force microscopy techniques and a strong interest in the other field is essential.
- Experience in numerical nonlinear dynamic techniques. In particular, harmonic balance method, continuation packages such as AUTO or COCO, or system identification.
- A good publication record.
- High motivation for teamwork and good communication skills.
Experience in signal processing using FPGA, experimental dynamics of MEMS/NEMS, or molecular dynamics will be additional valued knowledge.
