Photoionization cross section in a spherical quantum dot: Effects of some parabolic confining electric potentials
A theoretical investigation of the effects of spatial variation of confining electric potential on photoionization cross section (PCS) in a spherical quantum dot is presented. The potential profiles considered here are the shifted parabolic potential and the inverse lateral shifted parabolic poten...

Представлено теоретичне дослiдження впливу просторової змiни обмежуючих електричних потенцiалiв на перерiз фотоiонiзацiї в сферичнiй квантовiй точцi. Розглянутi тут профiлi потенцiалiв є змiщений параболiчний потенцiал i дзеркальне зображення змiщеного параболiчного потенцiалу, якi порiвнюються з добре вивченим параболiчним потенцiалом. Основний результат — це те, що параболiчний потенцiал i дзеркальне зображення змiщеного параболiчного потенцiалу зсувають пiки перерiзу фотоiонiзацiї у фiолетовий дiапазон, тодi як змiщений параболiчний потенцiал спричинює червоний зсув. 2017 Article Photoionization cross section in a spherical quantum dot: Effects of some parabolic confining electric potentials / M.

| description |
A theoretical investigation of the effects of spatial variation of confining electric potential on photoionization
cross section (PCS) in a spherical quantum dot is presented. The potential profiles considered here are the
shifted parabolic potential and the inverse lateral shifted parabolic potential compared with the well-studied
parabolic potential. The primary findings are that parabolic potential and the inverse lateral shifted parabolic
potential blue shift the peaks of the PCS while the shifted parabolic potential causes a red shift. |
