Microsphere-coupled light emission control of van der Waals heterostructures
Hyunseung Lee, Van Tu Nguyen, Ji-Yong Park +1
Two-dimensional transition metal dichalcogenides (TMDCs) integrated to photonic structures provide an intriguing playground for the development of novel optoelectronic devices with…
Imaging ultrafast carrier transport in nanoscale devices using femtosecond photocurrent microscopy
B. H. Son, Jae-Ku Park, J. T. Hong +3
One-dimensional nanoscale devices, such as semiconductor nanowires (NWs) and single- walled carbon nanotubes (SWNTs), have been intensively investigated because of their potential…
Band Structure, Phonon Scattering and the Ultimate Performance of Single-Walled Carbon Nanotube Transistors
Xinjian Zhou, Ji-Yong Park, Shaoming Huang +2
Semiconducting single-walled carbon nanotubes are studied in the diffusive transport regime. The peak mobility is found to scale with the square of the nanotube diameter and invers…
Electron-Phonon Scattering in Metallic Single-Walled Carbon Nanotubes
Ji-Yong Park, Sami Rosenblatt, Yuval Yaish +6
Electron scattering rates in metallic single-walled carbon nanotubes are studied using an atomic force microscope as an electrical probe. From the scaling of the resistance of the…
Electrical Nanoprobing of Semiconducting Carbon Nanotubes using an Atomic Force Microscope
Y. Yaish, J. -Y. Park, S. Rosenblatt +3
We use an Atomic Force Microscope (AFM) tip to locally probe the electronic properties of semiconducting carbon nanotube transistors. A gold-coated AFM tip serves as a voltage or c…
Tuning carbon nanotube bandgaps with strain
E. D. Minot, Yuval Yaish, Vera Sazonova +3
We show that the band structure of a carbon nanotube (NT) can be dramatically altered by mechanical strain. We employ an atomic force microscope tip to simultaneously vary the NT s…
