Motivation

Hybrid inorganic/organic semiconductor structures (HIOS) (see Sfb951) exhibit the potential to create novel opto-electronic systems by combining the strong light-matter coupling and the flexible HOMO-LUMO gap of organic materials with the high charge carrier mobility and the efficient electrical charge carrier injection of inorganic materials.

 

Targeted HIOS functions are:

I.   electrically pumped light/laser emission with versatile colour tunability

II.  light-electrical energy conversion

 

The targeted functions rely on efficient transfer of excitons and /or charges across the inorganic/organic interface. We work out strategies to control the geometric and electronic structure as well as the optical properties of the hybrid interface in order to optimize these transfer processes.

 

Our approach is:

   •HIOS preparation employing UHV deposition techniques.

   •In situ structural and electronic characterization by AFM/STM/KPFM.

   •In situ optical characterization by differential reflection spectroscopy.

   •CW and time-resolved optical spectroscopy, also in confocal geometry

  •Fabrication and testing of photovoltaic cells and light-emitting diodes.
