Extremely Slow Spontaneous Electron Trapping in Photodoped n-Type CdSe Nanocrystals

Arianna Marchioro

The trapping dynamics of conduction-band electrons in colloidal degenerately doped n-CdSe nanocrystals prepared by photochemical reduction (photodoping) were measured by direct optical methods. The nanocrystals show spontaneous electron trapping with distr ...

Quantum Mechanical Confinement in the Fin Electron-Hole Bilayer Tunnel Field-Effect Transistor

Mihai Adrian Ionescu, Cem Alper, José Luis Padilla de la Torre

Quantum mechanical confinement in electron-hole bilayer tunnel field-effect transistors (EHBTFETs) affects in a substantial way the band-to-band tunneling (BTBT) mechanism that constitutes their operating principle. Field-induced quantization is known to s ...

Switching Behavior Constraint in the Heterogate Electron–Hole Bilayer Tunnel FET: The Combined Interplay Between Quantum Confinement Effects and Asymmetric Configurations

Mihai Adrian Ionescu, Cem Alper, José Luis Padilla de la Torre

Switching behavior in electron-hole bilayer tunnel FETs is known to be unaffected by the subthreshold swing limitation of 60 mV/decade imposed by thermal injection, due to the band-to-band tunneling phenomena on which they rely. However, in this paper, we ...

Surface States Transport in Topological Insulator Bi0.83Sb0.17 Nanowires

Jean-Philippe Ansermet

We investigate the transport properties of topological insulator (TI) nanowires. Single-crystal nanowire samples with diameters ranging from 75 nm to 1.1 m are prepared using high frequency liquid phase casting in a glass capillary; cylindrical single crys ...

Magneto-ballistic transport in GaN nanowires

Elison de Nazareth Matioli, Dmitry Ovchinnikov, Adrien Victor Allain, Giovanni Santoruvo

The ballistic filtering property of nanoscale crosses was used to investigate the effect of perpendicular magnetic fields on the ballistic transport of electrons on wide band-gap GaN heterostructures. The straight scattering-less trajectory of electrons wa ...

Spin and Charge transport in Dirac Materials

Alexander Ronald Hoyer

The digitalization of our world is proceeding with every new technical product placed on the market. By making them smarter, e.g. linking them together and equipping them with sensors, a vast mass of data is collected. Processing and storing this informati ...

Observation of quantized conductance in neutral matter

Jean-Philippe Brantut

In transport experiments, the quantum nature of matter becomes directly evident when changes in conductance occur only in discrete steps1, with a size determined solely by Planck's constant h. Observations of quantized steps in electrical conductance2,3 ha ...

Mapping out spin and particle conductances in a quantum point contact

Jean-Philippe Brantut

We study particle and spin transport in a single mode quantum point contact using a charge neutral, quantum degenerate Fermi gas with tunable, attractive interactions. This yields the spin and particle conductance of the point contact as a function of chem ...

Electrochemical nanostructured biosensors: carbon nanotubes versus conductive and semi-conductive nanoparticles

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Gianluca Piccinini

The aim of this work was to demonstrate that various types of nanostructures provide different gains in terms of sensitivity or detection limit albeit providing the same gain in terms of increased area. Commercial screen printed electrodes (SPEs) were func ...
