Nature of the 1/f Noise in Graphene, Direct Evidence for the Mobility Fluctuations Mechanism
Adil Rehman, Juan Antonio Delgado Notario, Juan Salvador Sanchez +6
The nature of the low-frequency current fluctuations, i.e. carrier number vs. mobility, defines the strategies for noise reduction in electronic devices. While the 1/f noise in met…
Fast response photogating in monolayer MoS2 phototransistors
Daniel Vaquero, Vito Clericò, Juan Salvador-Sánchez +6
Two-dimensional transition metal dichalcogenide (TMD) phototransistors have been object of intensive research during the last years due to their potential for photodetection. Photo…
Excitons, trions and Rydberg states in monolayer MoS2 revealed by low temperature photocurrent spectroscopy
Daniel Vaquero, Vito Clericò, Juan Salvador-Sánchez +6
We investigate excitonic transitions in a h-BN encapsulated monolayer phototransistor by photocurrent spectroscopy at cryogenic temperature (T = 5 K). The spectra…
Evidence for an excitonic insulator phase in a zero-gap InAs/GaSb bilayer
W. Yu, V. Clericò, C. Hernández Fuentevilla +16
Many-body interactions can produce novel ground states in a condensed-matter system. For example, interacting electrons and holes can spontaneously form excitons, a neutral bound s…
Plasmonic terahertz detection by a double-grating-gate field-effect transistor structure with an asymmetric unit cell
V. V. Popov, D. V. Fateev, T. Otsuji +3
Plasmonic terahertz detection by a double-grating gate field-effect transistor structure with an asymmetric unit cell is studied theoretically. Detection responsivity exceeding 8 k…
Field Effect Transistors for Terahertz Detection: Physics and First Imaging Applications
W. Knap, M. Dyakonov, D. Coquillat +11
Resonant frequencies of the two-dimensional plasma in FETs increase with the reduction of the channel dimensions and can reach the THz range for sub-micron gate lengths. Nonlinear…
