Résumé offre printed OTFT : The PhD candidate will be joining the Institut d’Electronique et des Technologies du numeRique within the Organic and silicon systems (OASiS) team to work on the development of printed organic thin film transistors (OTFT). In particular, the PhD candidate will contribute in studying the replacement of heterojunction contacts (inorganic-organic) by homojunction ...

Résumé offre printed sensors : The PhD candidate will be joining the Institut d’Electronique et des Technologies du numéRique within the Organic and silicon systems (OASiS) team to work on the development of bio-inspired sensors. The candidat will take part in identifying natural and biodegradable materials, optimising the manufacturing processes and characterising and validating the printed sensors. INSTITUT ...

We report here the reversibility and bistability of the switching behavior in an azobenzene derivative induced by the bias applied by a scanning-tunneling microscopy (STM) tip, at low temperature and in ultra-high vacuum environment. This cis-to-trans and trans-to-cis switching were observed during STM imaging in either polarity at +2 V or −2 V, on a ...

There has been considerable interest in building switching functions into self-assembled monolayers with switching actuated by external stimuli such as light, electrical current, heat, pressure or chemical changes. In this study, dual switching functionality has been built into azobenzene based molecular monolayers. Switching behaviour has been compared for unsubstituted azobenzene monolayer adsorbates and two other ...

The optically tuneable nature of hybrid organic/inorganic heterostructures tailored by interfacing photochromic molecules with 2D semiconductors (2DSs) can be exploited to endow multi-responsiveness to the exceptional physical properties of 2DSs. In this study, a spiropyran-molybdenum disulfide (MoS2) light-switchable bi-functional field-effect transistor is realized. The spiropyran-merocyanine reversible photo-isomerization has been employed to remotely control both the ...

Submonolayer amounts of chloroaluminum-phthalocyanine on Cu(100) were studied with scanning tunneling spectroscopy. The molecule can be prepared in a fourfold symmetric state whose conductance spectrum exhibits a zero-bias feature similar to a Kondo resonance. In magnetic fields, however, this resonance splits far more than expected from the spin of a single electron. Density functional theory ...

Controlling the properties of 2D materials by defect engineering and atomic scale characterization by scanning tunneling microscopy   In this project, we will use scanning tunneling microscopy and spectroscopy (STM/STS) operating under ultra-high vacuum and at low temperature to study the structure and electronic properties of generated defects in 2D materials at the atomic scale. Substitutional atoms ...

Retour sur les premières Journée Plénières du GDR (26-28 Septembre 2022 ) Le 26-27 septembre 2022 s’est déroulée les premières journées plénières du GDR sur le site d’Odéon de l’université Paris Cité. Nous avons été ravis de vous accueillir pour ces premières journées et de l’avis de tous ces journées ont permis de réunir une bonne ...

Zinc hybrid supercapacitors (Zn-HSCs) hold immense potential toward the next-generation energy storage systems, effectively spanning the divide between conventional lithium-ion batteries (LIBs) and supercapacitors. Unfortunately, the energy density of most of Zn-HSCs has not yet rivalled the levels observed in LIBs. The electrochemical performance of aqueous Zn-HSCs can be enhanced through the chemical functionalization of ...
