Circular Dichroism Study of Colloidal Semiconductor Nanoscrolls

Аннотация

Chiral semiconductor nanoscrolls are promising materials for applications in chiral chemistry, biomedicine, and spintronics. Despite a large number of studies on the formation of nanoscrolls, there is lack of consistent theory of their optical and chiroptical properties. In this paper, we propose a simple analytical model of semiconductor nanoscrolls, based on the original coordinate transformation method and two-band effective mass approximation. This model allows to simulate absorption and circular dichroism spectra of nanoscroll of given geometry and material composition and to analyze experimental data.
