Michael Ruppert – Design of Hybrid Piezoelectric/Piezoresistive Cantilevers for Dynamic-mode Atomic Force Microscopy

Date & Venue Tuesday, 03 July 2018, 02:00PM EF122 Abstract Atomic force microscope cantilevers with integrated actuation and sensing on the chip level provide several distinct advantages over conventional cantilever instrumentation. These include clean frequency responses, the possibility of down-scaling and parallelization to cantilever arrays as well as the absence of optical interferences. However, the [...]

Steven Moore – Arbitrary placement of AFM cantilever higher eigenmodes using structural optimization

Date & Venue Tuesday, 26 June 2018, 02:00PM EF122 Abstract This talk presents a novel cantilever design approach to place higher mode frequencies within a specific frequency band to alleviate instrumentation and Q control feasibility. This work is motivated by the emerging field of multifrequency atomic force microscopy which involves the excitation and/or detection of [...]

Petter Ersbo – Displacement Estimation for Interferometry by Particle Filtering

Date & Venue Tuesday, 12 June 2018, 01:00PM EAG01 Abstract The current, least square (LS) based, method for displacement estimation was introduced 40 years ago. Today, computational power is much more readily available, which has opened up for the possibly employ novel and more advanced methods such as particle filtering. These methods may offer estimates [...]
