Summary: Ge1-xSnx nanocrystals are direct-gap semiconductors with tunable size and composition, showing enhanced optical properties and conductivity compared to pure Ge nanocrystals. By replacing insulating ligands with molecular metal chalcogenides, solution-processed conductive thin films can be produced, leading to significantly increased electrical conductivity. The alloying of Ge and Sn results in blue-shifted energy gaps and increased conductivity, making these nanocrystals promising for various optoelectronic applications.

Summary: The study demonstrates that coating a sub-200-nm-thick quantum dot film on two-dimensional materials can significantly enhance their nonlinear optical responses by more than three orders of magnitude. This enhancement is driven by a non-trivial mechanism of multiphoton-excitation resonance energy transfer, where the quantum dots deliver their strongly absorbed multiphoton energy to the adjacent two-dimensional materials.
