Objectives

Prepare the student for his dissertation work providing:

-a general overview of the scientific and/or technological basis necessary for the dissertation theme

chosen by the student, under indication of the direct supervisor(s)

-more in-depth practical information about laboratory techniques considered relevant to conducting

research work in materials science and engineering.

Subject matter

Bibliography review and introduction to the experimental work to be performed during the dissertation (under guidance of the supervisor of the dissertation).

Spectroscopic Impedance. Measurement methods. Analysis methods. Nyquist and Cole-Cole diagrams. Applications to polymer relaxation, semiconductor diodes and piezoelectrics.

X-ray Fluorescence Spectroscopy: XRF-WD and XRF-ED. Detection threshold and sensitivity. Detection systems. Chemical analysis by XRF. Lab session with the equipment AXIOS 4.0. Application of the programs SuperQ and IQ+.

X-Ray Diffraction. Introduction to the XRD equipments. Tests on samples from the students. Analysis and interpretation of the XRD tests. Determination of the crystallites size. Stress and texture analysis.

Atomic Force Microcopy AFM: type of equipment, modes of measurement. Tests on samples from the students. Analysis and interpretation of the tests.

Teaching method

 

Practical lab sessions comprising the performance of experimental work (FRX, DRX, AFM,Spectroscopic Impedance) specially oriented for the dissertation topics of the students.These sessions are lectured by specialists in each field from the CENIMAT

Bibliography review guided by the dissertation supervisor

Initiation to the research work of the dissertation (guided by the supervisor of each dissertation)

Students will present:

-report on each one of the 4 experimental techniques

-document where a bibliography review is made, data is presented relative to the initiation of the research work chosen for dissertation and, finally, a work-plan concerning the dissertation (to be performed during the 2nd. Semester); the presentation of this doc. is complemented by a public oral presentation, followed by discussion
