Graphene-capped bismuthene on SiC as a platform for correlated quantum spin Hall edge states
Huu Thoai Ngo, Zamin Mamiyev, Niclas Tilgner +4
Epitaxial bismuthene on SiC(0001) hosts symmetry-protected metallic edge states within a large bulk band gap, establishing it as a promising two-dimensional topological insulator f…
Intercalant-induced Kekule ordering and gap opening in quasi-free-standing graphene
Huu Thoai Ngo, Zamin Mamiyev, Niklas Witt +2
We present a comprehensive investigation of the structural and electronic properties of Sn intercalated buffer layers on SiC(0001) using low-temperature scanning tunneling microsco…
Monolayer-Defined Flat Colloidal PbSe Quantum Dots in Extreme Confinement
Leon Biesterfeld, Huu Thoai Ngo, Ahmed Addad +7
Colloidal two-dimensional lead chalcogenide nanocrystals represent an intriguing new class of materials that push the boundaries of quantum confinement by combining a crystal thick…
Sub-meV Linewidths in Polarized Low-Temperature Photoluminescence of 2D PbS Nanoplatelets
Pengji Li, Leon Biesterfeld, Lars Klepzig +11
Colloidal semiconductor nanocrystals are promising materials for classical and quantum light sources due to their versatile chemistry and efficient photoluminescence (PL) propertie…
