Excitonic insulator phase and dynamics of condensate in a topological one-dimensional model
Zahra Khatibi, Roya Ahemeh, Mehdi Kargarian
We employ mean-field approximation to investigate the interplay between the nontrivial band topology and the formation of excitonic insulator (EI) in a one-dimensional chain of ato…
Strain impacts on commensurate bilayer graphene superlattices: distorted trigonal warping, emergence of bandgap and direct-indirect bandgap transition
Zahra Khatibi, Afshin Namiranian, Fariborz Parhizgar
Due to low dimensionality, the controlled stacking of the graphene films and their electronic properties are susceptible to environmental changes including strain. The strain-induc…
Impacts of in-plane strain on commensurate graphene/hexagonal boron nitride superlattices
Zahra Khatibi, Afshin Namiranian, S. F. K. S. Panahi
Due to atomically thin structure, graphene/hexagonal boron nitride (G/hBN) heterostructures are intensively sensitive to the external mechanical forces and deformations being appli…
Dark-exciton based strain sensing in transition metal dichalcogenides
Maja Feierabend, Zahra Khatibi, Gunnar Berghäuser +1
The trend towards ever smaller high-performance devices in modern technology requires novel materials with new functionalities. The recent emergence of atomically thin two-dimensio…
Impact of strain on the excitonic linewidth in transition metal dichalcogenides
Zahra Khatibi, Maja Feierabend, Malte Selig +4
Monolayer transition metal dichalcogenides (TMDs) are known to be highly sensitive to externally applied tensile or compressive strain. In particular, strain can be exploited as a…
