Getting ready for the EOSBF

I finished today the preparation of the tutorial for the Autumn Meeting of the Brazilian Physical Society . I looking forward to give talk about molecular beam epitaxy: “MOLECULAR BEAM EPITAXY – A VERSATILE METHOD FOR THE NANO-AGE “. In this tutorial, I would like to give an overview of MBE covering its importance for …

Beamline paper out

Low-aberration beamline optics for synchrotron infrared nanospectroscopy Sync hrotron infrared nanospectroscopy is a recently developed technique that enables new possibilities in the broadband chemical analysis of materials in the nanoscale, far beyond the diffraction limit in this frequency domain. Synchrotron infrared ports have exploited mainly the high brightness advantage provided by electron storage rings across …

Workshop em cresimento epitaxial (LNNano)

There will be a workshop on epitaxy at the LNNano at the end of June. I will have the pleasure to give a talk and advertise the facility a bit. I will explain, what we do in research, but also what kind of structures can be realized inside a service/collaboration.   Hope to see you …

Back from the US

Back from the International Conference on Low-Dimensional Quantum Materials where I gave a talk about ” 2D nanomembranes as substrates for the growth of semiconductor nanostructures“. It was a very inspiring conference with excellent talks – I very much enjoyed the conversations with the other participates.  On the way back, I had a chance to …

Molecular beam epitaxy

For those interested in the technique of Molecular Beam Epitaxy, I will give a tutorial on the topic in Foz at the meeting of the Brazilian Physical Society. It will be great to give an overview to the possibilities and discuss current and future developments. I also like to advertise again the possibility to do …

Silicon Nanomembranes with Hybrid Crystal Orientations and Strain States

  Our publication investigating the structure of overgrown transferred silicon membranes is finally out: Have a look to “Silicon Nanomembranes with Hybrid Crystal Orientations and Strain States“. Methods to integrate different crystal orientations, strain states, and compositions of semiconductors in planar and preferably flexible configurations may enable nontraditional sensing-, stimulating-, or communication-device applications. We combine …

End of 2017

The year 2017 and the 2nd semester 2017 are about to end. It was fun teaching F329 and I am looking forward to do it again in the 1st semester of 2018. I’ll promise to try to in cooperate the feedback and improve the course – well the provas will have to stay, but I …

Correcting 1st prova of F329

Spending a lot of time, correcting the first test of F329. This made me think about, what and how we teach stuff. Which leads – in my case – unavoidably to think of a Terry Pratchett quote from the discworld cycle. “… therefore education at the (Unseen) University mostly worked by the age-old method of …

Paper out

Our paper regarding the interference of electrical signals to MFM measurements is out. First publications with Unicamp as affiliation. Have a look at: “Separating the influence of electric charges in magnetic force microscopy images of inhomogeneous metal samples“.

Last images of Cassini

Today Friday, NASA let the probe Cassini enter into the atmosphere of Saturn, where it burned. The probe was delivering nice images and a lot of scientific data for 13 years.  Even so not nanotechnology, I always had a great interest in this kind of science as it teaches us a lot about the world, …
