Ionic Gate Spectroscopy of 2D Semiconductors
Ignacio Gutiérrez-Lezama, Nicolas Ubrig, Evgeniy Ponomarev +1
Reliable and precise measurements of the relative energy of band edges in semiconductors are needed to determine band gaps and band offsets, as well as to establish the band diagra…
Synthetic Semimetals with van der Waals Interfaces
Bojja Aditya Reddy, Evgeniy Ponomarev, Ignacio Gutiérrez-Lezama +4
The assembly of suitably designed van der Waals (vdW) heterostructures represents a new approach to produce artificial systems with engineered electronic properties. Here, we apply…
Design of van der Waals Interfaces for Broad-Spectrum Optoelectronics
Nicolas Ubrig, Evgeniy Ponomarev, Johanna Zultak +14
Van der Waals (vdW) materials offer new ways to assemble artificial electronic media with properties controlled at the design stage, by combining atomically defined layers into int…
Enhanced electron-phonon interaction in multi-valley materials
Evgeniy Ponomarev, Thibault Sohier, Marco Gibertini +4
Through a combined theoretical and experimental effort, we uncover a yet unidentified mechanism that strengthens considerably electron-phonon coupling in materials where electron a…
Semiconducting van der Waals Interfaces as Artificial Semiconductors
Evgeniy Ponomarev, Nicolas Ubrig, Ignacio Gutiérrez-Lezama +2
Recent technical progress demonstrates the possibility of stacking together virtually any combination of atomically thin crystals of van der Waals bonded compounds to form new type…
Hole Transport in Exfoliated Monolayer MoS
Evgeniy Ponomarev, Árpád Pásztor, Adrien Waelchli +4
Ideal monolayers of common semiconducting transition metal dichalcogenides (TMDCs) such as MoS, WS, MoSe, and WSe possess many similar electronic properties. As it…
