Near-real-time diagnosis of electron optical phase aberrations in scanning transmission electron microscopy using an artificial neural network
Giovanni Bertoni, Enzo Rotunno, Daan Marsmans +4
The key to optimizing spatial resolution in a state-of-the-art scanning transmission electron microscope is the ability to precisely measure and correct for electron optical aberra…
Bandgap in orthorhombic thin lead halide perovskite (CsPbBr3) nanosheets measured from STEM-EELS
Rosaria Brescia, Stefano Toso, Quentin Ramasse +4
Inorganic lead halide perovskites are promising candidates for optoelectronic applications, due to their bandgap tunability, high photoluminescence quantum yield, and narrow emissi…
Imaging localized plasmon resonances in vacancy doped Cu3-xP semiconductor nanocrystals with STEM-EELS
Giovanni Bertoni, Rosaria Brescia, Luca De Trizio +2
Copper binary compounds are often intrinsic p-type semiconductors due to the presence of Cu(I) vacancies, with corresponding hole carriers in the valence band. If the free carrier…
Colloidal CuFeS2 Nanocrystals: Intermediate Fe d-Band Leads to High Photothermal Conversion Efficiency
S. Ghosh, T. Avellini, A. Petrelli +8
We describe the colloidal hot-injection synthesis of phase-pure nanocrystals (NCs) of a highly abundant mineral, chalcopyrite (CuFeS2). Absorption bands centered at around 480 and…
Influence of the Ion Coordination Number on Cation Exchange Reactions with Copper Telluride Nanocrystals
Renyong Tu, Yi Xie, Giovanni Bertoni +6
Cu2-xTe nanocubes were used as starting seeds to access metal telluride nanocrystals by cation exchanges at room temperature. The coordination number of the entering cations was fo…
