In the new carbonaceous sulfur hydride superconductor, with $T_c=287$ K at 267 GPa, the characteristic temperature is found to be 6239 K, implying a Debye temperature vastly exceeding that of metallic hydrogen. With the help of the Eliashberg–Nambu formalism and a generic model for the electron–phonon spectrum density, $0.92<\lambda <1.01$, $0.125<{\mathrm{\mu }}^{\ast }<0.179$, and $3.90<2{\Delta }_0∕k_B{T}_c<3.92$ are shown to be the most likely defining properties of the superconductor. The extraordinarily high Debye temperature and relatively low $\lambda$ indicate the importance of carbon may be comparable to or even eclipsing that of hydrogen in the pursuit of higher $T_c$ in ambient.

在新型碳质氢化硫超导体中， ${Ť}_C=287$K在267 GPa时，特征温度为6239 K，这意味着德拜温度大大超过了金属氢的温度。借助Eliashberg-Nambu形式主义和电子-声子谱密度的通用模型，$0。92<\lambda <\mathrm{1个}。01$， $0。125<{\mathrm{\mu }}^{\ast }<0。179$， 和 $3。90<\mathrm{2个}{\Delta }_0∕{ķ}_{乙}{Ť}_C<3。92$被证明是超导体最有可能定义的特性。德拜温度异常高而相对较低$\lambda$ 表明在追求更高的碳含量方面，碳的重要性可能与氢的重要性相媲美，甚至超过氢。 ${Ť}_C$ 在环境中。
