Science jobs from Université de Reims:
Electrodeposition of semiconducting nanowires using water and/or ionic liquid
Research activities at the LRN are focusing on the applications of nanostructured semiconducting materials following three main axes: nano-materials and applications (mainly nanowires/nanotubes growth and organic electronics) nano-characterization, development of original setups (near-field and electronic microscopies) nano-biotechnologies (use of QDs for targeting and diagnosis)
h1. Project details/job
The postdoctoral position opening in the lab will concern the electrodeposition activities of the laboratory, especially the growth of semiconducting nanowires/nanotubes. During the past years, the laboratory has developed an activity related to the growth of CdSe nanowires by "classical" electrodeposition in aqueous solution using polymer templates [1, 2], and a more original project related to the growth of Si, Ge and SiGe nanowires/nanotubes in ionic liquid [3,4].
The candidate will take in charge the electrodeposition work of the group (one Professor and one assistant professor) in collaboration with one PhD student in order to improve the electrodeposition processes and the properties of the different kind of NWs to use them in photoconducting and sensoring applications. As for the CdSe nanowires, the work will mainly be about functionalizing the NW surfaces so as to decrease the number of defects in order to be used as photodetectors. As for the Si, Ge applications which is the more important project, the goal of the applicant will be to understand the electrodeposition processes in ionic liquid so as to improve the control of the growth of the nanowires/nanotubes and their compositions (doping, alloying...). All the electrodeposition facilities are available in the lab and the candidate will also benefit from all the necessary characterization tools (TEM, SEM, AFM, DRX...). Depending on the results related to the growth of the nanowires, the candidate would have also the opportunity to participate to the application part of the project (NWs for sensing and photodetecting applications and Si nanowires as electrodes for high capacity electrode for Li Ion batteries.
h1. Preferred skills
The applicants should have strong background in electrochemistry/electrodeposition with knowledge in ionic liquid electrodeposition if possible, general activities in material sciences (including characterization techniques), and if possible some experience in surface chemistry.
Beginning of the contract as soon as possible for a first 18 month secured contract (around 2350 € gross/month)
Please send a CV, PhD report, Master's results, 2 recommendation letters and a motivation letter to Pr Michael Molinari (Michael.email@example.com) and Ass. Pr. Jeremy Mallet (Jeremy.firstname.lastname@example.org)
