Castellanos-Gómez Lab is kind of obsessed with cheap production techniques of 2D materials. They’ve proved this multiple times on the past by developing imaginative ways of producing and laying 2D materials over cheap substrates or using low-cost and accessible procedures. This time they’ve come up with a way to mechanically exfoliate van der Waals nanosheets […]
It’s been a few months without posting material. That doesn’t mean we haven’t been working! It is just that sometimes we can not talk about our projects due to clients privacy policies. And sometimes it is just that we have no time to do it. So we thought it would be a good idea to […]
We’ve been talking for quite a long time about the crazy things that happen in Andres Castellanos’s Lab. And they seem to be getting crazier. The ability of this people for outside the box thinking is amazing. Actually they don’t seem to know about the box at all! They are now working in the use […]
If I understand it correctly (and I’m probably not), Andres Castellanos is not only making interesting discoveries in condensed matter physics. He and his collaborators (Kavli Institute of Nanoscience and the University of Teheran) are also actively working on making it easier for others to make advances on this area. How? By making easier to […]
The Castellanos-Gómez Lab is an old friend of this website (and an old friend, period). And luckily for us, seems they never stop working at the highest level. This time they bring to the table a new way to engineer the biaxial strain in 2D materials. Their approach has been to create a tiny loop […]
Lets take a single layer of MoS2. Lets attach it to a surface in such a way that it can be stretched (or compressed) and there you have it: A strain tunable single-layer MoS2 photodetector. A device which uses strain to change the electrical and optical properties of 2D materials. In particular they’ve proven that […]
Measuring the mechanical strength of a material at the nanoscale is challenging . If the object we are measuring happens to be a two-dimensional material, the task amazingly difficult. But people at Castellanos-Gómez Lab are really smart. They’ve adapted a method (already used with organic thin films) to determine these materials Young Modulus that, apart […]
