2021年6月10日 · Hexagonal boron nitride (hBN), an atomically thin wide band gap two dimensional material, hosts robust, optically active luminescent point defects, which are known …

2019年7月12日 · Hexagonal boron nitride (hBN) is a highly anisotropic crystal, consisting of boron and nitrogen atoms strongly bonded in the in-plane direction. Because the difference in …

Hexagonal boron nitride (hBN) is a wide-band gap van der Waals material able to host light-emitting centers behaving as single photon sources. Here, we report the generation of color …

2024年10月4日 · Hexagonal boron nitride (hBN), as one of the few two-dimensional insulators, holds strategic importance for advancing post-silicon electronic devices and circuits. Achieving …

2025年1月1日 · Ren et al. [48] investigate the photoluminescence (PL) spectra of color centers within hBN-based heterojunctions. It reveals a sequence of PL spectra featuring peaks around …

2024年2月11日 · Single photon emitters from atomic defects in crystals like hexagonal boron nitride (hBN) are vital for quantum technologies. Although various techniques are devised to …

3 天之前 · The PL measurement of hBN:S film and hBN: Mg/hBN:S homojunction was fitted and illustrated in Figure 6d. In hBN systems, the unique optical property is that the defects-related …

2022年3月30日 · Our detailed theoretical calculations predict a giant bandgap renormalization and 0.7 eV exciton binding energy for monolayer hBN on graphene, matching our deep …

There was no discernible difference between the PL signal from the hBN/WS2 and the WS2/hBN structures. The dominant peak at ∼630 nm is due to the excitonic recombination in the WS2 …
