TL;DR: In this paper, the authors reported the direct observation of layer-hybridized moire excitons in angle-aligned WSe2/WS2 and MoSe2+WS2 superlattices by optical reflectance spectroscopy.

TL;DR: In this article, a single-pass optical parametric amplification at the ultimate thickness limit was demonstrated using semiconducting transition metal dichalcogenides, where an optical signal is amplified by a pump via the generation of an idler field.

TL;DR: The values of the open-circuit photovoltages and the flat-band potentials of the Si were a function of both the Fermi level of the graphene and the electrochemical potential of the electrolyte solution, indicating that the n-Si/Graphene did not form a buried junction with respect to the solution contact.

TL;DR: In this paper, a tunable second harmonic generation (SHG) from nanomechanically rotatable stacks of bulk hexagonal boron nitride (BN) crystals is presented.

TL;DR: A graphene nanosensor for affinity-based detection of low-charge, low-molecular-weight molecules, using glucose as a representative is presented, and can potentially be used in noninvasive glucose monitoring.
