Simple linear response model for predicting energy band alignment of two-dimensional vertical heterostructure
Javad G. Azadani, Seungjun Lee, Hyeong-Ryul Kim +4
The Anderson and midgap models are often used in the study of semiconductor heterojunctions, but for van der Waals (vdW) vertical heterostructures they have shown only very limited…
Tuning the doping of epitaxial graphene on a conventional semiconductor via substrate surface reconstruction
Miriam Galbiati, Luca Persichetti, Paola Gori +8
Combining scanning tunneling microscopy and angle-resolved photoemission spectroscopy, we demonstrate how to tune the doping of epitaxial graphene from p to n by exploiting the str…
High Brightness Lasing at Sub-micron Enabled by Droop-Free Fin Light-Emitting Diodes
Babak Nikoobakht, Robin P. Hansen, Yuqin Zong +3
Efficiency droop, i.e., a decline in brightness of LEDs at high electrical currents, has limited the performance of all commercially available LEDs. Until now, it has limited the o…
Bandstructure and Contact Resistance of Carbon Nanotubes Deformed by the Metal Contact
Roohollah Hafizi, Jerry Tersoff, Vasili Perebeinos
Capillary and van der Waals forces cause nanotubes to deform or even collapse under metal contacts. Using ab-initio bandstructure calculations, we find that these deformations redu…
Coherent plasmon and phonon-plasmon resonances in carbon nanotubes
Abram L. Falk, Kuan-Chang Chiu, Damon B. Farmer +5
Carbon nanotubes provide a rare access point into the plasmon physics of one-dimensional electronic systems. By assembling purified nanotubes into uniformly sized arrays, we show t…
Visualizing Band Offsets and Edge States in Bilayer-Monolayer Transition Metal Dichalcogenides Lateral Heterojunction
Chendong Zhang, Yuxuan Chen, Jing-Kai Huang +5
Semiconductor heterostructures are fundamental building blocks for many important device applications. The emergence of two-dimensional semiconductors opens up a new realm for crea…
