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, …

Tomorrow will be the first round of FI199 - mainly repeating basic solid state physics and talking about semiconductor devices. Hope already to introduce the heterostructure that we can talk about epitaxy and epitaxial semiconductor nanostructures next week.

Conference week

BWSP is coming up - beside the MBE tutorial by myself, the are two talks related to our work: Ingrid will talk about our work on rolled-up tubes and Evandro will show our results on charging on unstrained mesoscopic GaAs structures. See you there.

The IR beamline Synchrotron Radiation News article is out

The article describing the IR beamline of the LNLS is out. I was involved in setting up the experiments and also enjoyed in-house beamtime in the setup phase allowing to write our "Nanoscale" article on graphene/BN structures.  Synchrotron Radiation News is coined towards the community and should give a nice advertising to the beamline.

Teaching 2nd semester 2017

In my first semester at Unicamp, I will give F329 (Physics lab III) and contribute to FI199 with to lessons in August (Semiconductor nanostructures). Looking forward to do this. Hope, it will be better than in the xkcd strip below... I will announce office ours next week.

Back making rolled-up tubes

We are back to make rolled-up InGaAs/GaAs nano- and microtubes. We stopped doing the process for more than a year, but now is the time to strongly restart the activity. The light microscopy image shows one of our first process. The MBE grown sample coming from our machine rolls nicely, but we have to optimize …

AFM workshop at the LNNano

Scanning near field optical (SNOM) microscopy image of a graphene flak obtained during the AFM workshop at the LNNano using the NanoIR2-s system of the facility. We are back to the business of imaging garphene and restart this research line here as well as in collaboration with the CNPEM.   We had a lot of …

Beware the impact factor

I just read an interesting interview in a German Online magazine with Noble prize winner Randy Schekman. He warns to out to much value into the impact factor of magazines like "Science" and "Nature" - indeed he claims, they not helping science to progress, but give rise to fashionable and not-solid research. I agree with him: …

II LNNano AFM Workshop

WE will have our II LNNano AFM Workshop from the 05. to the 07. July at the LNNano. We had a tremendous feedback to the event. I am looking forward to do the theoretical course and will administrate one of the practical parts of the Workshop. The LCS group does a hard work making this …

Universal 01/2016 - Faixa B

After long waiting, we got the acceptance news for our Proposal of last year submitted in the Universal 01/2016 - Faixa B. We hope to start the project soon as it will supports our research on overgrowth of membranes and rolled-up nanotubes. The project tile is: " Nanoestruturas semicondutoras crescidas epitaxialmente sobre membranas para aplicações …
