Band structures of (NbSe)I and (TaSe)I: Reconciling transport, optics and ARPES
Irián Sánchez-Ramírez, Maia G. Vergniory, Claudia Felser +1
Among the quasi one-dimensional transition metal tetrachalcogenides (MSe)I (M=Nb,Ta), the compounds are the only ones not displaying charge density waves. Instead, th…
A new quasi-one-dimensional transition metal chalcogenide semiconductor (NbSeI)I
Kejian Qu, Zachary W. Riedel, Irián Sánchez-Ramírez +8
The discovery of new low-dimensional transition metal chalcogenides is contributing to the already prosperous family of these materials. In this study, needle-shaped single crystal…
Impact of electron-electron interactions on the thermoelectric efficiency of graphene quantum point contacts
Irián Sánchez-Ramírez, Yuriko Baba, Leonor Chico +1
Thermoelectric materials open a way to harness dissipated energy and make electronic devices less energy-demanding. Heat-to-electricity conversion requires materials with a strongl…
