a A photoluminescence spectrum of hBN/MoS2/hBN measured at room temperature. Excitation wavelength of 488 nm was used. b A photoluminescence image of hBN/MoS2/hBN. Bright part corresponds to encapsulated monolayer MoS2. The red dotted square shows the place where cleaning with contact-mode AFM...
The pure melamine sponge and hBN nanosheets present Raman shift at 972 cm−1, 1450 cm−1 and 1365 cm−1, respec- tively. The hBN-coated melamine sponge shows all those characteristic peaks in the spectrum, which implies hBN aeoxrfeifsectweend-ltaoeyrneertdehadethm1B3eN6la73m...
Followed by hydroxylation through ultrasonication, the silanization with 0.5mg/mL VTS resulted in weak absorbances between 1225鈥 995cm1 on FTIR spectrum, dispersed and translucent BN platelets, reduction of Raman peak intensity at 1368cm1, and an increase of zeta potential (from 10.1mV to 19.0mV...
The highest increase of the emission intensity is related to a double resonance, where the laser excitation is in resonance with the 2s A exciton of the WSe2 monolayer and the energy of the combined Raman scattering mode A 1 (WSe2) + ZO (hBN) is equal to the energy separation between ...
