巴黎第七大学 Prof. Jean Christophe LACROIX 实验室招2018 CSC 博士生 单位：ITODYS： nano electrochemistry 实验室 研究计划 Photo and redox active molecular layers for nanoelectronics Molecular electronics is a scientific domain, aiming at developing devices for information technologies. It uses pi-conjugated molecules deposited as ultrathin or monolayers, or in single molecule devices. In such systems, charge transport is mostly controlled by non-resonant tunnellingand depends poorly on the structure of the molecule. Molecular electronic has an obvious potential for extreme miniaturization, but has not yet allowed the production and the commercialization of devices due to several key issues that call for new approaches able to reach the adequate level of functionality, robustness, reliability, and fabrication yield. Electrochemistry in nanoscience can be used for building and studying nanostructured functional surfaces and nano-devices (atomic contact, organic and inorganic nanowires). Such systems are highlighted in the International Roadmaps of Semi-conducting Industry (ITRS) as the building blocks of emerging materials and devices. Electrochemistry in such solid state nanoelectronic devices is a new frontier and, as a consequence, a new field named “nano-electro-ionics” is now used to describe future devices that will impact the market in the next ten years. This PHD proposal lies within this context. It is focussed on emerging materials and devices as defined by the ITRS with a common theme as resistive memory and conductance switching. Based on the strong expertise already obtained by the group in these fields, it mainly focusses on breakthroughs that could be obtained using photo and redox active molecules in two terminal solid state devices. It has also long term economic perspectives with potentialities of impacting a multi-billion dollar markets. As an example, the present non-volatile solid state memory devices market reaches $100 billion/year. The main motivation of this project is to generate new building blocks that could be used in Metal/molecules/Metal devices with molecular layers 5-20 nm thick. Since this thickness range is much shorter than that in current organic electronic devices, the transport will be truly “nanoscale” and mainly intramolecular. Transport distances will be of the same order of magnitude compared to scattering or hopping lengths and charge carrier sizes. As a consequence transport will be almost activation-less and ultrafast. Since this thickness range is above the non-resonant tunneling limit, the transport will also be truly molecular and much more sensitive to the structural and electronic properties of the layer. We believe that this is a marked originality and novelty of the project. The fabrication process of the organic layers used in the proposal is based on electro-generated radical grafting processes using diazonium reduction. This process is becoming rapidly a versatile and efficient alternative to Self-Assembled Monolayers (SAM) on gold through thiol adsorption. It is now involved in many applications in the domains of materials, surface science and electronic. In the present proposal it is a key technology that makes it possible the direct evaporation of various metals on the grafted organic layer to fabricate the top electrode through fully CMOS-compatible processes. 上述是总体介绍，该课题已有更具体的研究方案，感兴趣的同学请直接联系导师咨询 Prof. Jean Christophe Lacroix Emails : Lacroix@univ-paris-diderot.fr 邀请信，学校offer，研究计划等导师都会帮忙准备，只要你达到了他的要求，有一定的语言基础和科研能力，有相关研究背景或有意此研究。要求： 化学或者物理化学背景，2018年7月份取得硕士学位，有托福或雅思成绩，CSC（公派）项目留学生. 单位：ITODYS： nano electrochemistry 实验室 我是2017年公派博士生，现在巴黎七大。小木虫账号出了点问题，借朋友的账号发帖。Prof.Lacroix是我的导师，他专注科研，认真负责，对每个学生的课题和研究进展都非常了解，会帮忙制定每一阶段的研究计划，基本每周都和学生讨论课题。他每年都有不少一区文章，在J. Am. Chem. Soc.等期刊上发表，可以google深入了解。他人很好，和蔼可亲，对学生的生活也常关心和照顾，对留学生更是热心提供帮助。Prof.Lacroix在2018年有招收一名CSC公派留学生的名额，感兴趣的同学尽快联系他，截止日期大概1月20号左右。在Prof.Lacroix这边读博，我感觉科研氛围较好，科研生活也很开心，所以很乐意帮他找到合适的学生，详情可邮件咨询Shierlly520@163.com。在此给有意出国读博的同学提供一个好的选择，希望大家抓住机会。 |
