The best time is the one you get to spend with your family. Don’t miss those chances. They won’t come back and you will regret it one day

Electron in a periodic potential

We are still accepting applications for a computational material scientist position on bands alignment in semiconductor heterostructures and other interesting projects (quantum dots, electrocatalysis, etc) app.ncoreplat.com/jobposition/68…

Lead Halide Perovskites Nanocrystals Synthesized in a Green, Reusable Solvent onlinelibrary.wiley.com/doi/10.1002/sm…

Both materials have the same number of valence electrons. On the left, the energy difference between bands is such that neither band is completely filled nor empty: a metal. On the right, one band is completely filled and the other is completely empty: an insulator/semiconductor

One issue with academic career is that it focuses on results rather than on understanding, with the assumption that getting results entails understanding, which is not always the case. So we may end up examining CVs of people who got many results but who understand almost nothing

Undistorted trans-polyacetylene: the 1D equivalent of graphene

The process of writing a paper is mainly a process of removing from the narrative all the biased and untested claims and stripping the story down to the minimal set of statements that can be backed by experimental data

Vertical optical transitions are allowed in a solid since all individual atomic transition dipoles are in phase. Non-vertical optical transitions are forbidden since atomic transition dipoles are out of phase. This is the equivalent of momentum conservation law!

Did you know? If relativity did not play a role, a piece of gold would look gray. Relativity contracts the 6s orbital & lowers its energy, and does the opposite with the 5d orbitals. Optical absorption, due to the 5d->6s transition, is in the blue, so the color of gold is yellow!

The famous E=mc^2 equation relating the energy of a particle with its rest mass has an unexpected companion in solids...In that case it relates the energy gap with the effective masses of the charge carriers.

Very proud of my group! Just a fraction of the group members in these two photos!

A book that every materials chemist should read from beginning to end, and I will never get tired of saying that.

We are used to think of metals as made of a "gas" of free electrons swirling around against a background of "fixed" positive ions. The question is why the electrons are so free to move and almost do not feel the presence of the positive ions. Here's the answer.
