Abstract:

Passivating molecules are introduced during the growth of semiconductor nanoparticles to arrest growth and prevent agglomeration. They also saturate dangling bond states, hence prevent mid-gap states which might occur otherwise. While these have been the conventional expectations of the passivating molecules, in this talk I will illustrate some of our recent work in which we show that they could play an ”active” role in determining the surface stoichiometry, contrary to the belief that they are passive bystanders.

The work is done in collaboration with Roby Cherian.
