A chemical vapor deposition method was developed to successfully synthesize layered crystals of PdSe2, a pentagonal 2D material, with exceptional optical and electrical properties approaching that of exfoliated crystals.
Significance and Impact
The scalable synthesis of novel 2D crystals to assess their anisotropic properties is essential for the rapid exploration and development of future electronic devices.
