Transfer characteristics of p-doped graphene/monolayer-MoS₂ heterostructure at 300 K are measured experimentally and analyzed based on a model calculation. In the model, we first discretize the Poisson equation into multiple zones. In each zone the charge density is assumed constant and the Poisson equation can be transformed into a linear equation to determine the chemical potential self-consistently. To calculate the electrical conductivity, we solve the Boltzmann transport equation in the relaxation-time approximation using the inelastic acoustic phonon scattering by solving the Dirac equation. The relationship between the Dirac voltage (the voltage at which the Fermi level is located at the Dirac point) and the Fermi energy (i.e. the initial chemical potential at 0 K) is derived. These calculations are performed without and with optical pumping and the results obtained agree well with the experimental data.

p掺杂石墨烯/单层MoS _2的转移特性实验测量300 K的异质结构，并基于模型计算进行分析。在模型中，我们首先将泊松方程离散化为多个区域。在每个区域中，电荷密度假定为常数，并且泊松方程可以转换为线性方程，从而自洽地确定化学势。为了计算电导率，我们通过求解狄拉克方程，使用非弹性声子散射来求解松弛时间近似中的玻耳兹曼输运方程。得出狄拉克电压（费米能级位于狄拉克点的电压）与费米能量（即0 K时的初始化学势）之间的关系。
