Polarization and charge-separation of moiré excitons in van der Waals heterostructures
Joakim Hagel, Samuel Brem, Ermin Malic
Twisted transition metal dichalcogenide (TMD) bilayers exhibit periodic moiré potentials, which can trap excitons at certain high-symmetry sites. At small twist angles, TMD lattice…
Stability of Wigner crystals and Mott insulators in twisted moiré structures
Daniel Erkensten, Samuel Brem, Raul Perea-Causin +1
Transition metal dichalcogenides (TMDs) constitute an intriguing platform for studying charge-ordered states including conventional and generalized Wigner crystals as well as Mott…
Quadrupolar Excitons in MoSe Bilayers
Jakub Jasiński, Joakim Hagel, Samuel Brem +11
The quest for platforms to generate and control exotic excitonic states has greatly benefited from the advent of transition metal dichalcogenide (TMD) monolayers and their heterost…
Electrically tunable layer-hybridized trions in doped WSe bilayers
Raul Perea-Causin, Samuel Brem, Fabian Buchner +6
Doped van der Waals heterostructures host layer-hybridized trions, i.e. charged excitons with layer-delocalized constituents holding promise for highly controllable optoelectronics…
Optical Signatures of Moiré Trapped Biexcitons
Samuel Brem, Ermin Malic
Atomically thin heterostructures formed by twisted transition metal dichalcogenides can be used to create periodic moiré patterns. The emerging moiré potential can trap interlayer…
Excitonic thermalization bottleneck in twisted TMD heterostructures
Giuseppe Meneghini, Samuel Brem, Ermin Malic
Twisted van der Waals heterostructures show an intriguing interface exciton physics including hybridization effects and emergence of moiré potentials. Recent experiments have revea…
