Theoretical investigation of the C-60/copper phthalocyanine organic photovoltaic heterojunction

Efthimios Kaxiras, Jun Ren, Sheng Meng

Molecular heterojunctions, such as the one based on copper phthalocyanine (CuPc) and carbon fullerene (C-60) molecules, are commonly employed in organic photovoltaic cells as electron donor-acceptor pairs. We have investigated the different atomic structur ...

Properties of copper (fluoro-)phthalocyanine layers deposited on epitaxial graphene

Efthimios Kaxiras, Jun Ren, Sheng Meng

We investigate the atomic structure and electronic properties of monolayers of copper phthalocyanines (CuPc) deposited on epitaxial graphene substrate. We focus in particular on hexadecafluorophthalocyanine (F16CuPc), using both theoretical and experimenta ...

Direct correlation of crystal structure and optical properties in wurtzite/zinc-blende GaAs nanowire heterostructures

Anna Fontcuberta i Morral, Martin Heiss, Emanuele Uccelli, Efthimios Kaxiras, Jun Ren, Sonia Conesa Boj

A method for the direct correlation at the nanoscale of structural and optical properties of single GaAs nanowires is reported. Nanowires consisting of 100% wurtzite and nanowires presenting zinc-blende/wurtzite polytypism are investigated by photoluminesc ...

Optical properties of clusters and molecules from real-time time-dependent density functional theory using a self-consistent field

Efthimios Kaxiras, Jun Ren, Sheng Meng

We present a detailed study of optical absorption spectra of finite-size structures, using a method based on time-dependent density-functional theory (TDDFT), which involves a self-consistent field for the propagation of the Kohn-Sham wavefunctions in real ...

Selective adsorption and electronic interaction of F16CuPc on epitaxial graphene

Efthimios Kaxiras, Jun Ren, Sheng Meng, Xi Chen

We investigate the electronic coupling between copper hexadecafluoro-phthalocyanine (F16CuPc) and epitaxial graphene (EG) on 6H-SiC (0001) using a combined approach of low-temperature scanning tunneling spectroscopy and electronic structure calculations. T ...
