Modular and Cost-effective Scanning Photocurrent Microscopy System for Sub-micron characterization of 2D optoelectronic devices
Nuria Jiménez-Arévalo, Dan Zheng, Yong Xie +8
Scanning photocurrent microscopy (SPCM) is a powerful technique for probing local optoelectronic phenomena in 2D semiconducting devices. However, commercial setups remain costly, c…
The Thermoelectric Effect and Its Natural Heavy Fermion Explanation in Twisted Bilayer and Trilayer Graphene
Dumitru Călugăru, Haoyu Hu, Rafael Luque Merino +3
We study the interacting transport properties of twisted bilayer graphene (TBG) using the topological heavy-fermion (THF) model. In the THF model, TBG comprises localized, correlat…
Evidence of heavy fermion physics in the thermoelectric transport of magic angle twisted bilayer graphene
Rafael Luque Merino, Dumitru Calugaru, Haoyu Hu +7
It has been recently postulated, that the strongly correlated flat bands of magicangle twisted bilayer graphene (MATBG) can host coexisting heavy and light carriers. While transpor…
Ultrafast Umklapp-assisted electron-phonon cooling in magic-angle twisted bilayer graphene
Jake Dudley Mehew, Rafael Luque Merino, Hiroaki Ishizuka +8
Carrier relaxation measurements in moiré materials offer a unique probe of the microscopic interactions, in particular the ones that are not easily measured by transport. Umklapp s…
Two-dimensional cuprate nanodetector with single photon sensitivity at T = 20 K
Rafael Luque Merino, Paul Seifert, Jose Duran Retamal +6
Detecting light at the single-photon level is one of the pillars of emergent photonic technologies. This is realized through state-of-the-art superconducting detectors that offer e…
A liquid nitrogen cooled superconducting transition edge sensor with ultra-high responsivity and GHz operation speeds
Paul Seifert, Jose Ramon Duran Retamal, Rafael Luque Merino +9
Photodetectors based on nano-structured superconducting thin films are currently some of the most sensitive quantum sensors and are key enabling technologies in such broad areas as…
