Dynamics of nonlinear optical rectification, second, and third harmonic generation in asymmetric triangular double quantum wells due to static electric and magnetic fields
Al, Emre Bahadır; Kasapoğlu, Esin; Ungan, Fatih (2022/4)In this study, we present a theoretical simulation of the impact of applied external electric and magnetic fields on the nonlinear optical rectification (NOR), second harmonic generation (SHG), and third harmonic generation ... -
Effect of size modulation and donor position on intersubbands refractive index changes of a donor within a spherical core/shell/shell semiconductor quantum dot
Al, Emre Bahadır (2021/9/24)In the current study, linear, nonlinear and total relative refractive index changes of a single shallow hydrogenic donor atom confined in semiconductor core/shell/shell quantum dot heterostructure are investigated in detail ... -
Electronic and optical properties of a D-2(+) complex in two-dimensional quantum dots with Gaussian confinement potential
Sarı, Hüseyin; Al, Emre Bahadır; Kasapoğlu, Esin; Şakiroğlu, Serpil; Sökmen, İsmail; Toro-Escobar, M.; Duque, Carlos Alberto (2022/4/1)Using the two-dimensional diagonalization method and the effective mass approximation, the electronic structure and intersubband optical absorption of the singly ionized double donor complex confined in a Gaussian quantum ... -
Shallow-donor impurity effects on the far infrared electron–electron optical absorption coefficient in single and core/shell spherical quantum dots with Konwent-like confinement potential
In this study, the electronic and optical properties of single or core/shell quantum dots, which are formed depending on the parameters in the selected Konwent potential, are investigated. Namely, the effects of the size ...
