In the framework of the adiabatic approximation strongly prolate and oblate conical quantum dots in the external electric field have been investigated. Analytical expressions for the particle wave function and energy spectrum are obtained for both cases. The dependencies of the absorption edge on the geometrical parameters and external field strength of conical quantum dots have been obtained. Selection rules are revealed for transitions between levels with different quantum numbers. The absorption coefficient dependence on the frequency of the incident light is revealed taking into account dispersion of conical quantum dot's base radius for Gaussian distribution function.

强长扁锥形量子点中电吸收的绝热描述
在绝热近似的框架内，已经研究了外部电场中的强扁长和扁锥形量子点。对于这两种情况，都获得了粒子波函数和能谱的解析表达式。已经获得了吸收边对锥形量子点的几何参数和外场强的依赖性。揭示了具有不同量子数的能级之间的跃迁的选择规则。考虑到锥形量子点基半径对于高斯分布函数的色散，揭示了吸收系数对入射光频率的依赖性。
