论文摘要
我们分析了石墨烯层（GLS）和石墨烯双层（GBLS）中准单喹啉的二维电子血浆的统计特征，并评估其热容量。弱抽水的固有或弱掺杂的GLS的GL热容量是由Boltzmann常数正常于boltzmann常数的$ c_ $ c_}的$ c_}。随着载体温度的变化，内在的GBL载体热容量$ c_ {gbl} $从$ c_ {gbl} \ simeq 2.37 $ at $ t \ lisesim 300 $ 〜k th $ c_ {gbl} \ simeq 6.58 $在高温下。这些值明显不同于经典的二维载体的热容量（$ c = 1 $）。获得的结果可用于优化不同基于GL和GBL的高速设备。
We analyze the statistical characteristics of the quasi-nonequilibrium two-dimensional electron-hole plasma in graphene layers (GLs) and graphene bilayers (GBLs) and evaluate their heat capacity.The GL heat capacity of the weakly pumped intrinsic or weakly doped GLs normalized by the Boltzmann constant is equal to $c_{GL} \simeq 6.58$. With varying carrier temperature the intrinsic GBL carrier heat capacity $c_{GBL}$ changes from $c_{GBL} \simeq 2.37$ at $T \lesssim 300$~K to $c_{GBL} \simeq 6.58$ at elevated temperatures. These values are markedly differentfrom the heat capacity of classical two-dimensional carriers with $c = 1$. The obtained results can be useful for the optimization of different GL- and GBL-based high-speed devices.
