A$_2$P$_2$S$_6$ (A = Ba and Pb): a good platform to study the polymorph effect and lone pair effect to form an acentric structure
Ji, Bingheng; Sarkar, Arka; Wu, Kui; Swindle, Andrew; Wang, Jian (The Royal Society of Chemistry, 2022-05-14)Three ternary thiophosphates α-Ba$_2$P$_2$S$_6$, β-Ba$_2$P$_2$S$_6$, and Pb$_2$P$_2$S$_6$ were synthesized via a high temperature salt flux method or an I2 transport reaction. β-Ba$_2$P$_2$S$_6$ and Pb$_2$P$_2$S$_6$ were ... -
Ba$_6$(Cu$_x$Z$_y$)Sn$_4$S$_{16}$(Z = Mg, Mn, Zn, Cd, In, Bi, Sn): High chemical flexibility resulting in good nonlinear-optical properties
Ji, Bingheng; Wu, Kui; Chen, Yunhua; Wang, Fei; Rossini, Aaron J.; Zhang, Bingbing; Wang, Jian (American Chemical Society, 2022-02-07)Seven acentric sulfides Ba$_6$(Cu$_x$Z$_y$)Sn$_4$S$_{16}$ (Z = Mg, Mn, Zn, Cd, In, Bi, Sn) were grown by a high-temperature salt flux method. The crystal structures of the Ba$_6$(Cu$_x$Z$_y$)Sn$_4$S$_{16}$ (Z = Mg, Mn, Zn, ... -
Centrosymmetric or Noncentrosymmetric? Transition Metals Talking in $K_2TGe_3S_8(T = Co, Fe)$
Ji, Bingheng; Pandey, Krishna; Harmer, Colin P.; Wang, Fei; Wu, Kui; Hu, Jin; Wang, Jian (American Chemical Society, 2021-07-01)Two new quaternary sulfides $K_2TGe_3S_8(T = Co, Fe)$ have been synthesized by a high-temperature solid-state routine and flux growth method. The crystal growth process of $K_2TGe_3S_8(T = Co, Fe)$ was elucidated by in ... -
d$^6$versus d$^{10}$, Which is better for second harmonic generation susceptibility? A Case Study of K$_2$TGe$_3$Ch$_8$ (T = Fe, Cd; Ch = S, Se)
Ji, Bingheng; Wang, Fei; Wu, Kui; Zhang, Bingbing; Wang, Jian (American Chemical Society, 2022-12-29)Two acentric chalcogenide compounds, K$_2$CdGe$_3$S$_8$ and K$_2$CdGe$_3$Se$_8$, were synthesized via conventional high-temperature solid-state reactions. The crystal structures of K$_2$CdGe$_3$S$_8$ and K$_2$CdGe$_3$S$_8$ ... -
Revisiting thiophosphate $Pb_3P_2S_8$: A multifunctional material combining a nonlinear optical response and photocurrent response
Ji, Bingheng; Guderjahn, Elizabeth; Wu, Kui; Syed, Tajamul Hussain; Wei, Wei; Zhang, Bingbing; Wang, Jian (Royal Society of Chemistry, 2021-09-30)$Pb_3P_2S_8$ was structurally characterized three decades ago with a second harmonic generation response. In this work, $Pb_3P_2S_8$ was revisited to investigate its electronic structure via DFT calculations and optical ... -
Revisiting two thiophosphate compounds constituting d\(_0\) transition metal HfP\(_2\)S\(_6\) and d\(_{10}\) transition metal α-Ag\(_4\)P\(_2\)S\(_6\) as multifunctional materials for combining second harmonic generation response and photocurrent response
Cropek, Craig; Ji, Bingheng; Sarkar, Arka; Wang, Fei; Syed, Tajamul Hussain; Wei, Wei; Guo, Sheng-Ping; Wang, Jian (The Royal Society of Chemistry, 2023-01-18)Two acentric thiophosphate compounds, HfP\(_2\)S\(_6\) and α-Ag\(_4\)P\(_2\)S\(_6\), are revisited and studied as infrared nonlinear optical materials. HfP\(_2\)S\(_6\) and α-Ag\(_4\)P\(_2\)S\(_6\) were structurally ...
