Competences to be gained during study

 

Basic competences

— Capacity to apply the acquired knowledge to problem-solving in new or relatively unknown environments within broader (or multidisciplinary) contexts related to the field of study.

— Capacity to integrate knowledge and tackle the complexity of formulating judgments based on incomplete or limited information, taking due consideration of the social and ethical responsibilities involved in applying knowledge and making judgments.

— Capacity to communicate conclusions, judgments and the grounds on which they have been reached to specialist and non-specialist audiences in a clear and unambiguous manner.

 

General competences

— Capacity to identify the scientific and industrial landscape in the immediate, national and international environment in the field of nanoscience and nanotechnology.

— Capacity to work independently, manage time and projects effectively, and acquire specific knowledge in order to gain entrance to doctoral programmes in nanoscience and nanotechnology.

 

Specific competences

— Capacity to recognize technological advances and current problems in the domain of nanotechnology as an interdisciplinary science.

— Ability to perform research and development tasks in relation to new nanostructured materials and nanodevices with innovative functionalities and potential applications in biotechnology, pharmacotherapy, information processing and storage, and improved energy use.

— Abilities and skills in the field of nanotechnology to establish future areas of research, development and production in companies associated with the field.

 

 

 

 

Learning objectives

 

Referring to knowledge

— Give an in-depth overview of the evolution of microelectronics until well into the 21st century. Introduce students to a reminder of advanced CMOS technology and the physics of the MOSFET transistor. Investigate deep submicron MOSFETs and describe physical and technological limits of miniaturization.

— Introduce students to short channel effects and quantum transport to understand the behaviour of modern devices. Investigate new materials such as High K-Low K and metal and silicides as substitutes of standard materials.

— Acquire a spirit of discovery and pushing the limits of technology and discuss solutions to keep up with miniaturization trend beyond Moore’s law. Describe advanced bulk and SOI processes of IBM and INTEL and nanolithography limitation of deep and extreme UV.

— Acquire an understanding of new physical processes and devices related with the nanoscale, such as balistic transport, Coulomb blockade, resonant tunnelling, nanomemories and single electron devices.

— Improve strategies in searching information, writing scientific reports and delivering oral presentation through a written assignment.

— Get to know the most advanced characterization tools in nanoelectronics at the Department of Electronics of the University of Barcelona, where students will design an experiment to measure nanoelectronic properties of a particular nanodevice.

Official assessment of learning outcomes

 

Continuous assessment
 

Assessment consists in an exam on basic concepts (50% of the final grade) and a project summarizing the state of the art and basic literature of a specific topic agreed with the lecturer. The project includes the preparation of a Power Point presentation (50% of the final grade). Students must attend at least 80% of the lectures, except for documented and justified special cases.

Repeat assessment

Students are entitled to repeat assessment only when have completed all the activities in the course.

 

Examination-based assessment

Students who wish to opt for single assessment must inform the coordinator of the subject and officially notify the coordinator of the master’s degree within the established deadlines. Mandatory activities must also be completed to be entitled to take the final exam.

Repeat assessment

Students who follow this modality are also entitled to repeat assessment only when have completed all the activities in the course.
