Paper from LNBE to be published in Physica E: Low-dimensional Systems and Nanostructures

The Physica E: Low-dimensional Systems and Nanostructures has accepted for publication a study on Photoconductivity of Composites Based on CdSe Quantum Dots and Low-band-gap Polymers by Sergey Daineko, Pavel Linkov, Igor Martynov, Pavel Samokhvalov, Igor Nabiev, and Alexander Chistyakov, of LNBE and Chair 81 of MEPhI performed together with colleagues from the Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences (IPCE RAS).

The authors have studied the photoconductivity of hybrid structures based on CdSe quantum dots and a low-band-gap polymer (PCDTBT or PTB7) obtained by the spin-coating method. They found that the photoresponse of the hybrid structures is mainly determined by the relative positions of the frontier energy levels of the two components. Since the energy level positions of quantum dots are determined by their size, the use of quantum dots in the hybrid material allows composites with controlled photoresponses to be fabricated. The optoelectronic and photovoltaic applications of the nanocomposites designed will make it possible to optimize photodetectors and photovoltaic cells based on these materials.

Physica E: Low-dimensional Systems and Nanostructures, published by Elsevier, focuses on review and research papers on basic and applied physics of low-dimensional systems, as well as heterostructures, quantum dots, supergratings, and other nanosystems. The journal is one of the world's leading periodicals in the physics of low-dimensional systems and nanostructures.
