“…24 This combination of properties makes it of interest for fundamental studies of anisotropic phenomena in 2D materials, but can also enable new types of applications such as acousto-optic modulators. 25 RESULTS AND DISCUSSION Structure and Characterization. Arsenic trisulfide, also known as orpiment, 26 is a naturally occurring layered crystal.…”

“…In addition to that, the material has perspectives to become an important member of the class of 2D materials due to a unique combination of properties: As 2 S 3 is known to transmit infrared well, has an optical indirect band gap of ∼2.6 eV, , shows photoconductivity, , and has a large acousto-optical figure of merit . This combination of properties makes it of interest for fundamental studies of anisotropic phenomena in 2D materials, but can also enable new types of applications such as acousto-optic modulators …”
