Exciton spectroscopy and diffusion in MoSe2-WSe2 lateral heterostructures encapsulated in hexagonal boron nitride
Dorian Beret, Ioannis Paradisanos, Ziyang Gan +17
Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures with potential applications in optoelectronics. Critical for carrier…
Well-defined sub-nanometer graphene ribbons synthesized inside carbon nanotubes
Hans Kuzmany, Lei Shi, Miles Martinati +9
Graphene nanoribbons with sub-nanometer widths are extremely interesting for nanoscale electronics and devices as they combine the unusual transport properties of graphene with the…
Proton and Li-Ion Permeation through Graphene with Eight-Atom-Ring Defects
Eoin Griffin, Lucas Mogg, Guang-Ping Hao +21
Defect-free graphene is impermeable to gases and liquids but highly permeable to thermal protons. Atomic-scale defects such as vacancies, grain boundaries and Stone-Wales defects a…
Templated direct growth of ultra-thin double-walled carbon nanotubes
Lei Shi, Jinquan Wei, Kazuhiro Yanagi +5
Double-walled carbon nanotubes (DWCNTs) combined the advantages of multi-walled (MW-) and single-walled (SW-) CNTs can be obtained by transforming the precursors (e.g. fullerene, f…
Extraction of Linear Carbon Chains Unravels the Role of the Carbon Nanotube Host
Lei Shi, Kazuhiro Yanagi, Kecheng Cao +3
Linear carbon chains (LCCs) have been shown to grow inside double-walled carbon nanotubes (DWCNTs) but isolating them from this hosting material represents one of the most challeng…
Efficient first principles simulation of electron scattering factors for transmission electron microscopy
Toma Susi, Jacob Madsen, Ursula Ludacka +6
Electron microscopy is a powerful tool for studying the properties of materials down to their atomic structure. In many cases, the quantitative interpretation of images requires si…
