SERS Substrate Fabrication via Rapid Triboelectrification‐Driven Self‐Assembly of Close‐Packed Colloidal Monolayers Triboelectrification-driven self-assembly of dry colloidal powder offers a promising dry approach to rapidly (<20$<20$ s) attain ordered monolayer colloidal particles for surface-enhanced Raman spect....

#Monolayers are cool, but not always better. In journals.aps.org/prl/abstract... we show that MoTe2-#bilayers have a brighter telecom-IR emission than monolayers, when stuck in an optical cavity. This makes them interersting for telecom-wavelength single photon sources.
