波尔半径 meaning in English
bohr radius
bohr rafdius
Examples
- Nanoparticles show significant quantum - size effect ( such as energy band discreteness , band gap broadening , blue shift in spectra etc . ) as sizes of particles are smaller than bohr radis of exciton of bulk material with same composition ( for example , cds ’ s bohr radium is 6nm )
当纳米粒子的尺寸小于其块状材料的激子波尔半径时(如cds的激子波尔半径为6nm ) ,能够表现出明显的量子尺寸效应(如能带离散,禁带变宽,光谱蓝移等) 。 - In the paper , by fractional - dimension space model , the relationships between system dimensions and wells width in zno / mgzno quantum well will be studied and the exciton dynamics such as wave functions , radial intensity and bohr radius in zno / mgzno with different well width are studied firstly . secondly , the system dimension , exciton wave functions and absorption spectrum in hexagonal microtube zno film were calculated and simulated , and the confinement of microtube is discussed . then the hexagonal microtube zno films are investigated by capacitance - voltage ( c - v ) measurements and the structure of zno / si were analyzed and modeled
本文利用分数维空间模型，首先研究了zno / mgzno量子阱中系统维度、激子波函数、径向密度和波尔半径随阱宽的变化，从中反映了zno / mgzno量子阱中量子尺寸效应对激子态的影响；其次计算和仿真得到六棱微管zno薄膜的系统维度、激子波函数及吸收谱，讨论了微管壁厚对激子的限制情况。
