Heralded Spectroscopy: a new single-particle probe for nanocrystal photophysics

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Samuel Burri, Arin Can Ülkü

Semiconductor nanocrystals feature multiply-excited states that display intriguing physics and significantly impact nanocrystal-based technologies. Fluorescence supplies a natural probe to investigate these states. Still, direct observation of multiexciton ...

Aptamer-field-effect transistors for small-molecule sensing in complex environments

Nako Nakatsuka

Aptamer-functionalized field-effect transistor (FET) biosensors enable detection of small-molecule targets in complex environments such as tissue and blood. Conventional FET-based platforms suffer from Debye screening in high ionic strength physiological e ...

Quantum dynamics of dissipative Kerr solitons

Vincenzo Savona, Fabrizio Minganti, Riccardo Rota, Kilian Robert Seibold

Dissipative Kerr solitons arising from parametric gain in ring microresonators are usually described within a classical mean-field framework. Here, we develop a quantum-mechanical model of dissipative Kerr solitons in terms of the Lindblad master equation ...

Incidence of Quantum Confinement on Dark Triplet Excitons in Carbon Nanotubes

The photophysics of single-wall carbon nanotubes (SWCNTs) is intensively studied due to their potential application in light harvesting and optoelectronics. Excited states of SWCNTs form strongly bound electron-hole pairs, excitons, of which only singlet e ...

Electronic transport across quantum dots in graphene nanoribbons: Toward built-in gap-tunable metal-semiconductor-metal heterojunctions

Oleg Yazyev, Kristians Cernevics, Michele Pizzochero

The success of all-graphene electronics is severely hindered by the challenging realization and subsequent integration of semiconducting channels and metallic contacts. Here, we comprehensively investigate the electronic transport across width-modulated he ...

In-situ reflectometry to monitor locally-catalyzed initiation and growth of nanowire assemblies

Anna Fontcuberta i Morral

We investigate in-situ laser reflectometry for measuring the axial growth rate in chemical vapor deposition of assemblies of well-aligned vertical germanium nanowires grown epitaxially on single crystal substrates. Finite difference frequency domain optica ...

Quantized Hall Conductance of a Single Atomic Wire: A Proposal Based on Synthetic Dimensions

Jean-Philippe Brantut

We propose a method by which the quantization of the Hall conductance can be directly measured in the transport of a one-dimensional atomic gas. Our approach builds on two main ingredients: (1) a constriction optical potential, which generates a mesoscopic ...

Ultrathin Junctionless Nanowire FET Model, Including 2-D Quantum Confinements

Farzan Jazaeri

In this paper, we develop an explicit model to predict the dc electrical behavior in ultrathin surrounding gate junctionless (JL) nanowire field-effect transistors (FETs). The proposed model considers 2-D electrical and geometrical confinements of carrier ...

Band and Correlated Insulators of Cold Fermions in a Mesoscopic Lattice

Jean-Philippe Brantut, Thierry Giamarchi, Samuel Häusler

We investigate the transport properties of neutral, fermionic atoms passing through a one-dimensional quantum wire containing a mesoscopic lattice. The lattice is realized by projecting individually controlled, thin optical barriers on top of a ballistic c ...
