摘要:

研究了由三个量子点组成的以圆心为三角形的量子分子。在纳米系统中的电子波函数是使用轨道量子阱的线性组合写入的。建立了量子分子中电子定态数值计算的色散方程,并对由三个球形量子点组成的分子中的电子能谱进行了数值计算。研究了量子分子的尺寸、间距和对称性对电子能谱的影响。等边三角形和等腰三角形对称的情况下被认为是。

英文摘要:

The quantum molecule consisting of three quantum dots that forms a triangle with its centers is studied. The electron wave function in the nanosystem is written using the linear combination of orbital quantum wells. The dispersion equation for numerical calculations of the electron stationary states in a quantum molecule is found. A numerical calculation of the electron energy spectrum in the molecule formed by three quantum dots of a spherical shape is carried out. The influence of the nanocrystal size, the distance between them and the symmetry of the quantum molecule on the electron energy spectrum is studied. The cases of symmetry of an equilateral and an isosceles triangle are considered.
