@SamirLounis6 @fz_juelich @RWTH @unidue @martin Congratulations, professor Lounis!! :D

[Jose Martinez Castro @JoseM_C_]

It is my pleasure to present this paper to the 2D community on which I had the opportunity to contribute. It is an amazing work which was carried out by Honey Boban https://t.co/LNQGc9pDVZ

@Andres_2DMat @mreyescalvo @icmm_csic @2d_foundry @UA_Universidad Thanks! Very interesting! Now I wonder why the SC transition of NbSe2 broadens so much with uniform compressive strain, that is puzzling...

@Andres_2DMat @mreyescalvo @icmm_csic @2d_foundry @UA_Universidad Another problem I had in the past, how did you manage to prevent the gold from cracking upon strain? I also played with deposited metals on polymers and that was a frequent problem that I observed!

[Jose Martinez Castro @JoseM_C_]

@Andres_2DMat @mreyescalvo @icmm_csic @2d_foundry @UA_Universidad and I noticed that when unclamped they tend to wrinkle. I was also wondering how you could distinguish wrinkling vs proper strain transfer since the two substrates have differen adhesion to the flake.

How? You just need Japanese cling wrap, a glove box and a bit of patience! Check the paper to know all the details. @fz_juelich @2dmp_spp2244

Assembly of Arbitrary Designer Heterostructures with Atomically Clean Interfaces https://t.co/XjUQwhTaBf

[Jose Martinez Castro @JoseM_C_]

The mechanical assembly of heterostructures is known to be a relatively dirty technique. It requires the use of polymers which tend to contaminate everything they touch...

[Jose Martinez Castro @JoseM_C_]

In this paper we offer a solution. We can pick up flakes and assemble heterostructures in a way that one side doesn't see any polymer at all and we can demonstrate that they are ultra clean!

[Jose Martinez Castro @JoseM_C_]

But what if you work in the field of surface science? Wouldn't it be great to find a way to assemble heterostructures on which the surface is a sensitive material?

[Jose Martinez Castro @JoseM_C_]

This is not extremely problematic if one for instance does transport. You can always encapsulate your materials with h-BN and contact it with graphene whiskers.

@WillkePhilip @ERC_Research Congratulations Philip!

@semontis @SubhashishB19 I tried to get into it, it’s wonderful but also a very complicated program with a very steep learning curve. I realised I would need three months to do something useful and let it go :/
