Circular dichroism in non-chiral metal halide perovskites
Peter C. Sercel, Zeev Valy Vardeny, Alexander L. Efros
We demonstrate theoretically that non-chiral perovskite layers can exhibit circular dichroism (CD) in the absence of a magnetic field and without chiral activation by chiral molecu…
Bright triplet excitons in lead halide perovskites
Michael A. Becker, Roman Vaxenburg, Georgian Nedelcu +13
Nanostructured semiconductors emit light from electronic states known as excitons[1]. According to Hund's rules[2], the lowest energy exciton in organic materials should be a poorl…
Tight-binding calculations of image charge effects in colloidal nanoscale platelets of CdSe
R. Benchamekh, N. A. Gippius, J. Even +6
CdSe nanoplatelets show perfectly quantized thicknesses of few monolayers. They present a situation of extreme, yet well defined quantum confinement. Due to large dielectric contra…
Coulomb gap in the one-particle density of states in three-dimensional systems with localized electrons
A. L. Efros, Brian Skinner, B. I. Shklovskii
The one-particle density of states (1P-DOS) in a system with localized electron states vanishes at the Fermi level due to the Coulomb interaction between electrons. Derivation of t…
High volumetric capacitance near insulator-metal percolation transition
A. L. Efros
A new type of a capacitor with a very high volumetric capacitance is proposed. It is based upon the known phenomenon of a sharp increase of the dielectric constant of the metal-ins…
Electronic states and optical properties of PbSe nanorods and nanowires
A. C. Bartnik, Al. L. Efros, W. -K. Koh +2
A theory of the electronic structure and excitonic absorption spectra of PbS and PbSe nanowires and nanorods in the framework of a four-band effective mass model is presented. Calc…
