Description du sujet

This project is part of the international collaboration with NTU (Taipei, Taiwan) and the establishment of an international laboratory between Grenoble and NTU starting this year for 5 years (2021-2025) on glycopolymer self-assembly and applications in transistor memories. The objective of this project is the design and nanofabrication of novel oligosaccharide-based block copolymers with high segregation strength to control the size, orientation and long-range order of domains for the next generation of high-resolution sub-10 nm patterns. This "window" of opportunity will certainly open new horizons for the valorization of these new bio-based functional nanomaterials and an approach ready to be implemented on new and innovative devices.

This collaborative project aims at developing the design of new thin films from the self-assembly of carbohydrate block copolymer systems with high performance for stretchable transistor memory devices. These new systems were found to be novel biomaterials and to have a strong electronic affinity capable of trapping negative charges.

 

1)-Synthesis of bio-sourced block copolymers with different architectures: Precise synthesis of polymers (Month: 1- 18): Synthesis by click chemistry of bio-sourced copolymers with controlled architecture and their characterizations by different techniques (NMR, GPC, Mass Spectrometry, IR, TGA, DSC, DMA and TMA)

2)- Self-assembly properties, structural stability in relation with structural parameters- Months : 12- 24 : Preparation and characterization of nanostructured films by Imaging : TEM, Cryo-TEM, SEM and AFM - and the use of synchrotron radiation (ESRF) : SAXS /WAXS and GISAXS

3rd step: Measurement of electrical properties Month: 12-36: (in collaboration with NTU, Taipei)-Electrical characterization and performance optimization of the memory device based on biobased copolymers

4th step : A stretchable memory device with high performance transistors Month : 18- 36 (in collaboration with NTU, Taipei): The proposed biobased copolymer films will be integrated into stretchable transistor memory devices

 

Event - Objective outcome(s) setting the end of the PhD work:

1)-Synthesis of novel bio-based copolymer systems with controlled architecture.

2)-Self-assembly of these systems in the form of ultra-nanostructured films (sub_10nm)

3)-Integration of these highly nanostructured films in memories with stretchable transitors

4)- Dissemination of the results in the form of Patents/Publications/Conferences

-

Modalities of evaluation and control of the achievement of the result(s) :

1)-Maintain and update daily the laboratory notebook

2)Weekly meeting and regular follow-up of the project progress - and in VisioConference with NTU

3)-Missions to NTU (Taipei) for presentation of results and discussion

Présentation établissement et labo d'accueil

Université Grenoble Alpes

The CERMAV is a research center on naturel macromolecules with 140 people. It is structured around 5 research teams whose expertise ranges from carbohydrate chemistry to biomaterials science. The CERMAV's originality and strength are based on an approach combining fundamental and applied research. The multidisciplinary approach covers specialties ranging from chemistry, physical chemistry and biology, which allows it to occupy today an important place, at the international level, in the flagship field of glycosciences, ranging from complex carbohydrates (sugars, oligo- and polysaccharides, glycopolymers and glycomaterials) involved in biological processes and health, to biosourced materials

The PhD student's host team, "Self-assembly of glycopolymers" led by Redouane Borsali (CNRS Research Director), is composed of about fifteen people (3 CNRS researchers, 1 CNRS engineer and about ten Post-docs, PhD students and Masters). This team is interested in the physical chemistry and self-assembly of biosourced copolymers for the design of nanostructured films and glyconanparticles for bionoelectronic applications. His national and international collaborations are multiple and in particular these last years with Asia (Japan, Taiwan and China).

Profil du candidat

The candidate should preferably have a Master 2 in materials science, nanoscience or polymers with ideally some knowledge in copolymer chemistry. Previous experience in the preparation and physicochemical characterization of self-assembled copolymer-based structures would be appreciated.

 

A demonstrated ability to work across the boundaries of chemistry and physics, and excellent communication and writing skills (English) are equally important criteria for academic qualifications and scientific merit in the selection of the doctoral student. Studies and follow-up of scientific publications, regular reporting and presentation of activities, co-authorship of scientific articles/patents, dissemination of results, writing of the thesis report and defense of the PhD
