To investigate hydrostatic pressure and temperature effects on electron energy levels of an InAs spherical segment quantum dot with wetting layer embedded in GaAs barrier, we use the finite element method to solve the Schrödinger equation in the effective mass approximation. Results show that the ground, the first and the second excited state energies decrease (increase) as the hydrostatic pressure (temperature) increases for the constant temperature (pressure). Moreover, given the optical properties of the system interacting with two laser fields, red (blue) shifts are observed in the linear and nonlinear absorptions and dispersions for the probe pulse as the hydrostatic pressure (temperature) increases. Furthermore, as the hydrostatic pressure increases, the maximum of the group velocity of light inside the slow light frequency range increases and the slow light frequency range shifts to the lower probe frequencies.

温度和静水压力对电子结构，球形段量子点/润湿层的光学性质和光群速度的影响

为了研究静水压力和温度对GaAs势垒中嵌入润湿层的InAs球形段量子点的电子能级的影响，我们使用有限元方法在有效质量近似中求解Schrödinger方程。结果表明，在恒定温度（压力）下，随着静水压力（温度）的增加，地面，第一和第二激发态能量减少（增加）。而且，鉴于系统的光学特性与两个激光场相互作用，随着静水压力（温度）的增加，在探测脉冲的线性和非线性吸收和色散中观察到红（蓝）移。此外，随着静水压力的增加，
