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 our process to place them on the sample surface and to control the roll-up.

In the past, this was not to hard and I hope, we be back to the excellent structures, we fabricated before, very soon.

These structures are related to our ongoing FAPESP project and we would always welcome another helping hand in the whole thing. We are still interested in doing hybrid radial superlattices and try to explore further functionality of the tubes.
