The effect of the substrate on the Raman and photoluminescence emission of single layer MoS2
Michele Buscema, Gary A. Steele, Herre S. J. van der Zant +1
We quantitatively study the Raman and photoluminescence (PL) emission from single layer molybdenum disulfide (MoS2) on dielectric (SiO2, hexagonal boron nitride, mica and the polym…
Deterministic transfer of two-dimensional materials by all-dry viscoelastic stamping
Andres Castellanos-Gomez, Michele Buscema, Rianda Molenaar +4
Deterministic transfer of two-dimensional crystals constitutes a crucial step towards the fabrication of heterostructures based on artificial stacking of two-dimensional materials.…
Long-range Scanning Tunneling Microscope for the study of nanostructures on insulating substrates
Aday Molina-Mendoza, José Gabriel Rodrigo, Joshua Island +4
The Scanning Tunneling Microscope is a powerful tool for studying the electronic properties at the atomic level, however it's relatively small scanning range and the fact that it c…
Submicrosecond-timescale readout of carbon nanotube mechanical motion
H. B. Meerwaldt, S. R. Johnston, H. S. J. van der Zant +1
We report fast readout of the motion of a carbon nanotube mechanical resonator. A close-proximity high electron mobility transistor amplifier is used to increase the bandwidth of t…
Local strain engineering in atomically thin MoS2
Andres Castellanos-Gomez, Rafael Roldán, Emmanuele Cappelluti +4
Tuning the electronic properties of a material by subjecting it to strain constitutes an important strategy to enhance the performance of semiconducting electronic devices. Using l…
Fast and reliable identification of atomically thin layers of TaSe2 crystals
Andres Castellanos-Gomez, Efrén Navarro-Moratalla, Guillermo Mokry +7
Deposition of clean and defect-free atomically thin two-dimensional crystalline flakes on surfaces by mechanical exfoliation of layered bulk materials has proven to be a powerful t…
