Design and synthesis of molecular semiconductors resilient to energetic disorder

Université Libre de Bruxelles is hiring a first stage researcher within the framework of the UHMob MSCA ITN action (GA n°811284).

Please find a detailed offer and requirements below.

OFFER DESCRIPTION

Université Libre de Bruxelles – Free University of Brussels – (ULB) is a major academic institution with international recognition for scientific achievements.

Geerts group works on the design, the synthesis, and the processing of molecular semiconductors into highly ordered thin films to enhance charge transport properties.

PhD thesis to be conducted within 3 years at ULB, in the frame of UHMob.

Research topic: It is well-established from temperature-dependent charge transport measurement that mobility values are limited by structural disorder, inducing energetic disorder. Low temperature measurements afford mobility ranging from 100 to 300 cm2/Vs. It is, however, possible to engineer molecular and crystal structure of semiconductors to reach situations in which electronic coupling between adjacent molecules cause a restricted energetic disorder. It is intended to design by theory such materials, to synthesise them in sufficient amount and purity, and to distribute them for charge transport measurements.  

Research field(s): Chemistry, Molecular Chemistry, Organic Electronics, Organic Synthesis, Aromatic Chemistry, Physical Chemistry, Crystal growth, Crystallography

SECONDMENTS

Scheduled research stays abroad (secondments):

  • 3 months at the University of Mons (Belgium)
  • 6 months at Kyoto University (Japan)
