It is recommended to have passed the first full course (Introducció a la Nanociència i la Nanotecnologia, Enllaç Químic i Estructura de la Matèria, i Reactivitat Química) and the followong form the second course: Termodinàmica, Cinètica i Transformacions de Fase, Química Orgànica, Química del Elements i laboratori de microscòpies i caracterització.
It is also recommended to be studying at the same time, or previously, the third year course: Síntesi i Estructura de Materials Cristal·lins i Amorfs.
The objective of this course is to introduce the Surface Science to students, an interdisciplinary science and boundary between physics, chemistry, biology and engineering. The most basic aspects of the chemophysical phenomena that take place at the liquid-gas, solid-liquid, solid-gas and solid-solid interfaces will be treated. Several concepts previously introduced in previous years to students, in course like "Introduction to Nanoscience and Nanotechnology" and "Laboratory of microscopes and characterization of materials" will be deepen in this course. Knowledge in chemistry and Thermodynamics will be used to address surface phenomena, interface and heterogeneous catalysis, discussing also the different types of catalysts. Surface structure of solids as well as their modification, will be studied along with main surface characterization techniques. Surface characterization from a structural, morphological, microstructural and compositional point of view will be described in detail. The techniques for thin film deposition will be introduced, highlighting the importance of epitaxial growth in nanotechnology applications.
Module A (Dr. José A. Ayllón)
1. Introduction to surfaces.
- Liquid surfaces. Surface tension. Techniques measure surface tension. Capillary condensation.
- Thermodynamics of interfaces. Gibbs Isotherm.
2. Adsorption. Electrified surface
- Physisorption and chemisorption. Adsorption isotherms. Gas adsorption. Adsorption kinetics
- Electrode solution interface. Corrosion Electrolysis
3. Heterogeneous catalysis.

Module B (Dr. Gemma Garcia)
4. Structure and modification of solid surfaces
- 4.1. Notation of surface structures
- 4.2. Superficial reconstruction
- 4.3. Structure of adsorbed monolayers
5. Techniques of surface characterization
- 5.1. Spectroscopy AES, XPS
- 5.2. Proximity microscopies: AFM, STM, SPM
6. Crystalline growth of thin layers.
- 6.1. Nucleation and growth from vapor phase - Epitaxy
The course consists of: 28 hours of theory + 14 hours of problems + 10 hours of laboratory, per student.
Lectures
They will be carried out combining the use of material in digital format and the board. The teaching staff will present practical cases in order to exemplify the application of various theories and models.
Problem sessions
Participation of the students during the classes of problems will be promoted. Some problem sessions will take place in a group. When the teacher determines it, the delivery of resolved problems will be mandatory. When the teacher determines it, hours of problems can be used to carry out continuous evaluation tests.
Laboratory practices
The practices are compulsory, no unjustified absence will be accepted.
The previous work of reading scripts and revision of the theoretical contents will be fundamental for the good resolution of the problems and the practices.
- Module A will carry out two laboratory practices sessions of 3 hours.
- Module B will hold a practical session of 4 hours.
Tutorials
The faculty staff will be available for consulting queries of students. The use of this didactic resource is strongly recommended.

The global assessment will be carried out continuously and consists of:
- 1 partial about the contents of Module A, whose mark will be 40% of the final grade. (obligatory)
- 1 partial on the contents of Module B, whose mark will be 40% of the final grade. (obligatory)
- 1 delivery of problems and / or reports of practices, individual or in group, of Module A, whose mark will be of 10% of the final grade.
- 1 delivery of problems and / or reports of practices, individual or in group, whose note will be of 10% of the final grade.
IMPORTANT: In order to pass the subject it will be necessary to: I / have an overall grade equal to or higher than 5.0 and II / have obtained at least 5.0 points out of 10 on the average of the two partial tests. When the continuous assessment is not passed, in breach of either of these two criteria, but a minimum of 3.5 is obtained in the overall subject, you will be entitled to a written test of recovery on the contents of the two modules (partial ) that will allow to approve the asignatura (note of 5 out of 10).
