Amorphous chalcogenide thin films: photoinduced phenomena

Provider: Grantová agentura ČR
Programe: Standard projects
Duration: 2015-01-01 – 2017-12-31
Workpkace: Faculty of Chemical Technology
Guarantor: doc. Ing. Petr Němec, Ph.D.
Co-gurarantor:
The aim of the project is using advanced physical methods of thin films deposition (pulsed laser deposition, radio-frequency magnetron sputtering, etc.) for the fabrication of thin amorphous chalcogenide films. Prepared thin films will be studied from the point of view of photoinduced changes proceeding during exposure with light having energy close to band gap energy. The attention will be paid also to searching for photostable chalcogenide thin films. Photoinduced effects/photostability will be investigated in order to evaluate influence of chemical composition of the thin films, used deposition method, and deposition conditions. The results of the project will contribute to deepen the fundamental knowledge about photoinduced phenomena in amorphous chalcogenides.

Autonomous identification system for detection and security of the products for the system Industry 4.0

Provider: Technologická agentura České republiky
Programe: EPSILON
Duration: 2017-01-01 – 2019-12-31
Workpkace: Faculty of Chemical Technology
Guarantor: Ing. Tomáš Syrový, Ph.D.
Technology of the continuous production of the printed memories elements and their implementation into flexible labels will be suggested. These labels enable high level of the product security and identification for the full automatized and robotized production and distribution process required by Industry 4.0 system. The security data will not be possible to change or forge and it will integrate the rewritable memory for the preservation of data enable to follow the product during its life cycle. Electronic security element will be supplemented by unique visual element. Reading device including software will be developed during the project for the reading and identification of the specific data stored in the memory system. Data will be read by contact way.
 

 

Heterostructures based on chalcogenides for nonlinear optics and optical sensors

Provider: Grantová agentura ČR
Programe: Standard projects
Duration: 2016-01-01 – 2018-12-31
Workpkace: Faculty of Chemical Technology
Guarantor: Virginie Nazabal, Dr.
The main target of the project is to employ advanced thin film preparation techniques (pulsed laser deposition, magnetron sputtering) for the fabrication of high-quality heterostructures based on chalcogenide materials. The final goal will be to fabricate and characterize heterostructures for environmental or medical detection and nonlinear optical devices. The fabrication of thin amorphous chalcogenide films and their detailed characterization will be investigated in the frame of the project. The study of heterostructures will be performed considering the compatibility of silicon, dielectric materials as SiO2, Al2O3 and gold with chalcogenides and the optimization of interfaces between the different layers. The results of the project will contribute to deepen the fundamental knowledge about the thin film fabrication processes and their use in the field of photonics. It is expected that obtained results will clearly demonstrate the ability of fabricated chalcogenide-based heterostructures for use in nonlinear optical devices and optical sensors.
 

 

Innovation of laboratory equipment for the branch of Graphic Arts (Department of Graphic Arts and Photophysics)

Provider: Ministerstvo školství, mládeže a tělovýchovy
Programe: Internal development competition
Duration: 2017-01-01 – 2017-12-31
Workpkace: Faculty of Chemical Technology
Guarantor: Ing. Bohumil Jašúrek, Ph.D.
Co-gurarantor:
The project is concerned with the innovation of lab. equipment used in study programs in branch of Graphic Arts. New equipment will replace old one, which is in an unsatisfactory condition. The equipment would be used mainly in lab. tasks of four subjects (Lab. Pract. in Printing Techn. II and IV, Special Projects in Printing Techn. I and II), and in the measurement of experimental parts of bachelor and diploma thesis. Lab. equipment is essential for characterisation of properties of printing materials (papers, fountain solutions, inks, etc.). Within lab. exercises, emphasis is placed on developing students' skills to solve practical problems and the processing of each task is to deepen the theoretical knowledge with practical experience. Approval of the project would allow the improvement of the educational process, which is conditional on the use of modern equipment, devices, materials and standards. It will increase the practical preparedness of students and their employability.
 

 

X-ray photoelectron spectroscopy characterization and plasma etching structuration of amorphous chalcogenides

Provider: Ministerstvo školství, mládeže a tělovýchovy
Programe: Francie - Barrande
Duration: 2017-01-01 – 2018-12-31
Workpkace: Faculty of Chemical Technology
Guarantor: prof. Ing. Petr Němec, Ph.D.
In the frame of the project, high quality chalcogenide glasses and their amorphous thin films Ge-(As, Sb)-Se-(Te) will be fabricated by pulsed laser deposition and by RF magnetron sputtering. The fabricated layers will be characterized in terms of the structure (XPS, Raman spectroscopy), morphology (AFM, SEM-EDX), and optical properties (spectroscopic ellipsometry). Fundamental knowledge on the etching mechanisms of chalcogenide glasses in high density plasmas will be obtained. In particular surface structure of chalcogenide thin films will be explored by XPS before, during, and after inductively coupled plasma etching. Plasma processes of potential interest for device patterning will be identified. Elementary patterns will be etched to evaluate their application.
