In this work, a hexagonal quantum dot (HQD) with hydrogenic donor impurity was considered. We have first employed the finite element method (FEM) to determine energy eigenvalues and eigenstates of the system. Then, we have calculated the binding energy, absorption coefficients (ACs), refractive index changes (RICs), diamagnetic susceptibility, entropy and specific heat of the system under influence of impurity location. It is found that (1) total ACs and RICs show a maximum value at an especial impurity location and the properties have a blue or red shift with changing the impurity position. (2) The influence of impurity position on the electronic, optical and thermodynamic properties of a HQD is considerable. (3) The absolute value of diamagnetic susceptibility with impurity is lower than it without impurity. (4) The specific heat shows a peak structure in the presence of impurity. The peak position of specific heat depends on impurity location and temperature. (5) Entropy is reduced in the presence of impurity.

在这项工作中，考虑了带有氢供体杂质的六角形量子点（HQD）。我们首先采用了有限元方法（FEM）来确定系统的能量本征值和本征态。然后，我们计算了在杂质位置的影响下系统的结合能，吸收系数（ACs），折射率变化（RICs），抗磁化率，熵和比热。发现（1）总的AC和RIC在特定的杂质位置处显示最大值，并且随着杂质位置的改变，性质具有蓝色或红色偏移。（2）杂质位置对HQD的电子，光学和热力学性质的影响很大。（3）具有杂质的抗磁化率的绝对值低于没有杂质的抗磁化率的绝对值。（4）比热在存在杂质的情况下显示峰结构。比热的峰值位置取决于杂质的位置和温度。（5）在杂质的存在下熵降低。
