Surface alloy with sulfur leading piezoelectricity from non-piezoelectricity of pentagonal-PdPSe

Enabling enhanced lithium storage capacity of two-dimensional pentagonal BN2 by aluminum doping

“…23,24 Recent research has shown that doping can alter important properties, such as inducing piezoelectricity in penta -PdPSe which was previously non-piezoelectric. 25 For battery application, Chen et al 26 have reported a large (2183 mA h g −1 ) theoretical storage capacity and a low Li diffusion energy barrier (0.14 eV) in penta -BCN. However, by comprehensively considering the structural anisotropy of penta -BCN, Ananchuensook et al 27 have recently found that the maximum Li specific capacity is only 1455 mA h g −1 .…”
