2. 1. Microscopic modelling of exciton-exciton interactions in atomically thin semiconductors

   Author : Daniel Erkensten; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; transition-metal dichalcogenides; dark excitons; density matrix formalism; exciton-exciton interactions;

   Abstract : The successful isolation and characterization of the technologically promising material graphene in 2004 has spurred huge interest in other two-dimensional materials. Transition-metal dichalcogenides (TMDs), being one such class of materials, display intriguing properties from both a fundamental and techno- logical point of view. READ MORE

4. 2. Quantum Theory of Exciton-Exciton Interactions in Atomically Thin Semiconductors

   Author : Daniel Erkensten; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; excitons; transition-metal dichalcogenides; many-body theory; van der Waals heterostructures; 2D materials;

   Abstract : Atomically thin materials such as transition-metal dichalcogenides (TMDs) have emerged as an unprecedented platform for engineering future optoelectronic devices and studying exotic quantum phases of matter. In particular, the strong Coulomb interaction in these materials enables the formation of tightly-bound excitons, electron-hole pairs with neither purely fermionic nor bosonic character. READ MORE
