The group of Dr. Červinka at the University of Chemistry and Technology Prague, Czechia (@CervinkaGroup, https://sites.google.com/view/cervinkagroup) calls for a PhD student in the field of computational chemistry. This position is opened in connection to a JUNIOR STAR research project funded by the Czech Science Foundation.

Organic semiconductors represent a broad material class offering interesting properties such as potential biocompatibility, large structural variability, mechanical flexibility, or transparency. These promising properties, however, cannot outweigh insufficient conductivity of the organic matter when compared to crystalline silicon, which impedes wider spread of alternatives to the traditional inorganic platforms for optoelectronic devices. This work will concern development and applicability testing of quantum-chemical methods for modelling polymorphism of molecular crystals similar to relevant organic semiconductive materials. Larger molecular size, high degree of conjugation and frequent heterocyclic nature of the target molecules represent the challenges that the computational chemistry has to face in order to provide accurate description of molecular interactions in this field. Crystal structure prediction, accurate quantum-chemical treatment of the non-covalent interactions, their relationship to the bulk structure, and the stability ranking of individual polymorphs at various conditions will be targeted within this thesis. Finally, an interpretation of the impact of subtle variations of bulk structure on the charge-carrier mobility in organic semiconductors will be searched for.

We offer
