Just out in @NatureNano 🌟 We show that individual dopants in WSe2 bilayers can act as point-like photovoltaic junctions, generating nanoscale photocurrent and enabling exciton dissociation over ~1 nm. #2Dmaterials #photovoltaics #WSe2 nature.com/articles/s41565-0…

New paper in @acsnano 📢 We observe exciton-enhanced shift current in monolayer MoS2, revealing pronounced contributions from higher-order excitons and strong electrical tunability of the nonlinear photocurrent. #2Dmaterials #excitons #shiftcurrent doi.org/10.1021/acsnano.6c01…

Just out in @NanoLetters 📢 We find that the nonlinear optical response of few-layer CrPS₄, an antiferromagnetic semiconductor, is sensitive to its spin configuration, enabling microscopic imaging of Néel vectors. #2Dmaterials #antiferromagnetic pubs.acs.org/doi/10.1021/acs…

New paper in @acsnano ✨ With electron ptychography, we push imaging resolution to 0.35Å, visualizing the intriguing defect nucleation of 1D defects and their dynamic rearrangement in monolayer MoS2—🔬 #defects #2Dmaterials #4DSTEM #ptychography pubs.acs.org/doi/10.1021/acs…

Just out in @NatureComms ✨ We show that excitons bound to individual Nb impurities in monolayer WS₂ act as single-photon emitters with well-defined energies. Ultradilute doping is key to unlocking these quantum effects. #2Dmaterials #Doping nature.com/articles/s41467-0…
