Direct optical absorption in cylindrical quantum dot with rectangular infinitely high confinement potential A.S. Amiryan, H.A. SarkisyanArmenian State Engineering University, Yerevan, ArmeniaIn given article direct optical absorption in cylindrical quantum dot with rectangular infinitely high confinement potential is theoretically investigated. According to [1] absorption coefficient is defined by the formula
where
The corresponding selection rules for optical transitions are defined. The expressions for absorption threshold frequencies are found. The obtained results are compared with the case of light direct optical absorption in spherical quantum dot.
