Moduli

Metodi di valutazione

Tipo di esame: 
Orale
Modalita' di verifica dell'apprendimento: 

The teacher assesses if and to what extent the student has reached the course objectives.
A formal knowledge-based evaluation of the general topics delivered. The examination is performed through an oral exam .
The students can do a mid term test: a class presentation of about 15 minutes on a topic selected by the students from a list that the teacher will give at about the end of March of each year. This presentation will count for 30 % of your final grade

Obiettivi formativi

Joining fundamental concepts of the solid state and surface physical chemistry with applicative issues in the science and technology of semiconductors.

Knowledge and understanding

At the end of the course the student knows:

- The main characterization techniques for material and surface properties

- the main growth processes for semiconductor bulk material and thin films

- the role of defects on material properties with a focus to semiconductor

Applying knowledge and understanding

At the end of the course the student is able to:

- to apply a method to understand and to predict the role of defects on material properties based on the chemical physics concept of solid solution

- is able to analyse the results of surface and material characterization carried out with several characterization techniques such as SEM, EDX, XPS, SIMS

-to know that any growth techniques could introduces defects which can modified the materials properties and the devices related performances

-to know the role and the importance of the defects in material science

Making judgements

At the end of the course the student is able to:

- to choose the best growth method and characterization techniques to be used accordind to the properties and functionality of the material he/she wants to have or to investigate

-To avoid any contamination sources or to control them

Communication skills

To be able to describe and to explain orally with a suitable language the subjects of the class and to to sustain a contradictory on the basis of judgment abilities developed autonomously on class issues.

Learning skills

To be able to apply the acquired knowledge to contexts different from those presented during the course, and to understand the topics covered in the scientific literature concerning the the defectivity in the materials and the complex relationship among the growth processes and the material properties
