Charge transport in organic semiconductor: From principles to devices.
Prof. Emanuele Orgiu
Université du Québec – Canada
Abstract:
Charge transport in organic semiconductors is notoriously extremely sensitive to the presence of disorder, both internal and external (i.e., related to interactions with the dielectric layer), especially for n-type materials. Internal dynamic disorder stems from large thermal fluctuations both in intermolecular transfer integrals and (molecular) site energies in weakly interacting van der Waals solids and sources transient localization of the charge carriers. The molecular vibrations that drive transient localization typically operate at low-frequency (<a-few-hundred cm−1), which makes it difficult to assess them experimentally. Hitherto, this has prevented the identification of clear molecular design rules to control and reduce dynamic disorder. In addition, the disorder can also be external, being controlled by the gate insulator dielectric properties. During the seminar, I will give a few examples of charge transport in very closely related molecular organic semiconductors using a combination of temperature-dependent inelastic neutron scattering and photoelectron spectroscopy corroborated by electrical measurements, theory, and simulations . Unambiguous evidence that ad hoc molecular design enables the electron charge carriers to be freed from both internal and external disorder to ultimately reach band-like transport is provided.

Os jornais do Physical Review e dicas para autores
Dr. Katiuscia N. Cassemiro
Managing editor – PRX Quantum
Abstract:
O que fazer para ter seu artigo aceito para publicação? Apresentarei os jornais da American Physical Society, Physical Review, com ênfase em um dos novos jornais da família, PRX Quantum, que é de acesso público e voltado para a comunidade em ciências quânticas. Quando falamos em publicar um artigo, sabemos que é necessário não apenas excelência na execução da pesquisa—por parte dos autores—mas também de engajamento da comunidade de modo mais amplo, o que é facilitado pelos editores. Discutirei minha perspectiva quanto ao processo de revisão, clarificando a razão de certos procedimentos, e oferecendo algumas dicas para aprimorar seu próximo artigo e melhorar sua interação com pareceristas e editores.
