Накратко на български

Двуизмерни материали с атомарна дебелина се използват за създаване на устройства, които реагират на различни външни стимули, като например електрохимично управляван транзистор. Те предлагат алтернатива на силициевата електроника и помагат за намаляване на размерите на бъдещите електронни компоненти.

multireSponsive hybrid Transition mEtaL dichaLcogenides-bAsed optoelectRonics – A European Fellowship for career development

When Moore’s Law comes to an end, the further development of electronic devices requires exploring new research directions, including the breakthrough of physics limitation to realize ultimate scaling of device dimensions and the enrichment of device functionality to enable diversification. Two-dimensional (2D) materials with atomic level thickness and ultrahigh surface-to-volume ratio show the ability to ultimately scale down the device dimensions and provide a desirable platform to design novel functional devices. Therefore, 2D materials have been regarded as the promising semiconductor materials in next generation electronic devices. In the STELLAR project, we have developed a unique chemical approach to enrich the functionality of 2D optoelectronic devices. The development of novel 2D technology will offer an alternative solution to solve the great challenges in silicon electronics. The overall objectives of this project were to conduct high-quality research in the field of hybrid 2D optoelectronic devices to develop multiresponsive devices which can respond to multiple independent external stimuli. In summary, the STELLAR project provides a guideline to design light-responsive 2D devices and allowed the development of an electrochemically controlled 2D transistor for the first time. These new findings will bring technology revolution in the electronic industry.

Цел на проекта

STELLAR will offer world-class training through research in the cross-disciplinary and supra-sectorial field of 2D transition metal dichalcogenides (TMDCs)-based multiresponsive optoelectronics to an extremely talented and promising young researcher, with a PhD in physics and an extraordinary track record. The proposed research lies at the interface between physics, chemistry and electrical engineering, in the interdisciplinary realms of supramolecular sciences, materials science and nanoscience. The overall mission is to train the fellow to become an independent scientist and to prepare him for a leading position in academia/public sector or industry. The research programme in STELLAR targets a fundamental breakthrough in the field of 2D TMDCs by combining switchable molecular systems to construct multiresponsive hybrid molecules/TMDC structures and optoelectronic devices. For this purpose, TMDC nanosheets will be engineered via ion bombardment to create chalcogen vacancies as anchoring sites for molecules. Specially designed molecules with multiple responsive moieties (photochromic and electrochemically switchable moieties) and suitable head groups (thiol or selenol groups) will be chemisorbed on the defective TMDC surface. This novel hybrid system can respond to multiple independent external stimuli and exhibit distinct physical and chemical properties in different stable states. Electrolyte-gated field-effect transistors (FETs) with a hybrid molecules/TMDC channel will be exploited to realize multiresponsive optoelectronic devices. These FETs can be controlled or switched not only by gate voltage, but also by multiple external stimuli. Such smart devices can work as multi-bit memories, chemical sensors and diodes. In conclusion, STELLAR aims at developing high-performance multiresponsive optoelectronic devices with hybrid molecules/TMDC systems to replace the state-of-the-art Si-based and organic electronic devices.
