Memristive Control of Plasmon-Mediated Nonlinear Photoluminescence in Au Nanowires

Konstantin Malchow

Nonlinear photoluminescence (N-PL) is a broadband photon emission arising from a nonequilibrium heated electron distribution generated at the surface of metallic nanostructures by ultrafast pulsed laser illumination. N-PL is sensitive to surface morphology ...

Optimizing Atomic Layer Deposition Processes with Nanowire-Assisted TEM Analysis

Johann Michler, Ivo Utke, Xavier Maeder

Atomic layer deposition (ALD) is one of the premier methods to synthesize ultra-thin materials on complex surfaces. The technique allows for precise control of the thickness down to single atomic layers, while at the same time providing uniform coverage ev ...

Nanomechanical Modeling of the Bending Response of Silicon Nanowires

Yusuf Leblebici, Zuhal Tasdemir, Mohammad Nasr Esfahani, Mustafa Yilmaz

Understanding the mechanical behavior of silicon nanowiresis essentialfor the implementation of advanced nanoscale devices. Although bendingtests are predominantly used for this purpose, their findings shouldbe properly interpreted through modeling. Variou ...

Effect of Native Oxide on Stress in Silicon Nanowires: Implications for Nanoelectromechanical Systems

Yusuf Leblebici, Zuhal Tasdemir, Mohammad Nasr Esfahani

Understanding the origins of intrinsic stress in Si nanowires (NWs) is crucial for their successful utilization as transducer building blocks in next-generation, miniaturized sensors based on nanoelectromechanical systems (NEMS). With their small size lead ...

Controlled filamentation instability as a scalable fabrication approach to flexible metamaterials

Fabien Sorin, Pierre-Luc Eloi Piveteau, William Nicolas Duncan Esposito, Louis Marie Philippe Martin-Monier

Long and flexible arrays of nanowires find impactful applications in sensing, photonics, and energy harvesting. Conventional manufacturing relies largely on lithographic methods limited in wafer size, rigidity, and machine write time. Here, we report a sca ...

Generation of Human iPSC-Derived Neurons on Nanowire Arrays Featuring Varying Lengths, Pitches, and Diameters

Anna Fontcuberta i Morral, Wonjong Kim

Nanowire (NW) arrays interfaced with biological cells have been demonstrated to be potent tools for advanced applications such as sensing, stimulation, or drug delivery. Many implementations, however, have so far only been studied with rather robust basic ...

Focusing on the liquid role in the vapour liquid solid growth mechanism

Lea Ghisalberti

In this work we dive into key questions regarding the wetting of a nanoscale droplet which provides fundamental understanding of Vapor-Liquid-Solid growth mode of nanowires. This understanding is important to performreproducible NW fabrication and allow th ...

Doping challenges and pathways to industrial scalability of III–V nanowire arrays

Anna Fontcuberta i Morral, Lucas Güniat, Valerio Piazza, Wonjong Kim

Semiconductor nanowires (NWs) have been investigated for decades, but their application into commercial products is still difficult to achieve, with triggering causes related to the fabrication cost and structure complexity. Dopant control at the nanoscale ...

Theoretical Studies of Nanowire Ion-Sensitive Field Effect Transistor

Jean-Michel Sallese, Ashkhen Yesayan

The operation principle of a semiconductor nanowire (NW) ion-sensitive field-effect transistor (ISFET), denoted for pH sensing, is studied within the framework of this work. The physical processes in the system are mathematically modelled and presented in ...
