Solar-blind ultraviolet (SBUV) detection has important applications in wireless secure
communication, early warning, and so forth. However, the desired key device for SBUV …

Over the past 20 years, astro and solar physicists have been working hard to develop a new-
generation semiconductor-based vacuum-ultraviolet (VUV, 100–200 nm) photodetector with …

In recent years, there has been an explosive increase in the research on van der Waals
(vdW) crystals because of their great potential applications in many optoelectronic devices. It …

Millimeter-sized Cs4PbBr6 bulk single crystal that has no green luminescence was
successfully grown from concentrated CsBr aqueous solution for the first time. Absorption …

Unlike traditional three-dimensional semiconductors, when van der Waals semiconductors
are integrated to other materials,“lattice mismatch” in the vertical direction can be avoided …

Black phosphorus has a strong Raman anisotropy on the basal and cross planes due to its
orthorhombic crystal structure. However, almost all the studies on black phosphorus' …

Compared with photoconductive photodetectors (PDs), photovoltaic PDs not only have
higher response speed and stability in theory, but also have the advantage of operating …

Raman tensors, one of the basic physical properties of \rmMoS_2 MoS_2, are rarely
reported. Here, angle-resolved polarized Raman scatterings on basal and cross planes of …

Molybdenum selenide (MoSe2) is a van der Waals layered crystal with both the anisotropic
light absorption and light scattering outside its surface. At present, the study of the Raman …

Tungsten selenide (WSe2) as a van der Waals layered crystal has anisotropic light
absorption and light scattering on its out-of-plane surface. However, the Raman tensor of …
