Hooray! In a publication in ACS Nano Letters, André Saraiva and Belita Koiller demonstrate how to identify a pair of impurities in silicon, in analogy to the H2 molecule. The peculiarities of the Si conduction electrons permit to electrically contact and pass a current through this molecule. The result — extremely different from Ohm’s law, […]

Hooray!!! This issue of Environmental Science and Technology publishes an article by Rodrigo Capaz and our group’s collaborators from INMETRO. In this study, they take a step back from the usual interests of the group to discuss Terra Preta de Índio (Amazonian Dark Earths) a system of interest for soil and climate sciences. The soil […]

Hooray!!! Today’s cover at the Physical Review Letters electronic edition highlights the letter “Single-Shot Readout and Relaxation of Singlet and Triplet States in Exchange-Coupled P31 Electron Spins in Silicon”, in co-authorship with André Saraiva. A pair of isolated donors had its quantum state measured instantly through a method developed by the experimental group at University […]
