THE COURSE AIMS TO PROVIDE AN IN-DEPTH KNOWLEDGE OF THE PHYSICS AND TECHNOLOGY OF MODERN SEMICONDUCTOR ELECTRONIC DEVICES, PARTICULARLY THOSE WITH NANOMETRIC DIMENSIONS. KNOWLEDGE AND UNDERSTANDING: THE COURSE CONSTITUTES AN IN-DEPTH ANALYSIS OF THE ELECTRONIC, OPTOELECTRONIC AND TRANSPORT PROPERTIES OF SEMICONDUCTOR MATERIALS; IT DEALS IN AN EXTENSIVE MANNER THE MANUFACTURE, CHARACTERIZATION AND OPERATION OF DIODES, TRANSISTORS AND MEMORIES; FOCUSES ON ELECTROSTATIC AND SEMICLASSIC AND QUANTUM TRANSPORT PHENOMENA IN MODERN NANOTRANSISTORS; MENTIONS THE TRANSPORT PROPERTIES OF ONE- AND TWO-DIMENSIONAL NANO-STRUCTURED MATERIALS (NANOWIRE, NANOTUBE, GRAPHENE AND OTHER 2D MATERIALS); IT EXTENDS TO MICROWAVE DEVICES AND PHOTONIC DEVICES (PHOTOR DETECTORS, LASERS AND PHOTOVOLTAIC CELLS). STUDENTS ARE MADE AWARE OF THE TECHNOLOGICAL AND CONCEPTUAL CHALLENGES PRESENTED BY THE CONTINUOUS MINIATURIZATION OF ELECTRONIC DEVICES AND TRENDS IN MODERN NANOELECTRONICS. THE COURSE MAY INCLUDE A LABORATORY PART IN WHICH CUTTING-EDGE TECHNIQUES AND TOOLS ARE USED TO CARRY OUT ELECTRO-OPTICAL CHARACTERIZATIONS OF DEVICES. ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING: WITH THIS COURSE THE STUDENT WILL ACQUIRE THEORETICAL AND PRACTICAL KNOWLEDGE USEFUL FOR CARRYING OUT RESEARCH ACTIVITIES IN A MICRO AND/OR NANOELECTRONICS LABORATORY AND FOR UNDERTAKING WORK IN THE SEMICONDUCTOR INDUSTRY. THE STUDENT WILL CONSTANTLY USE THE ENERGY BAND MODEL TO UNDERSTAND THE ELECTRICAL BEHAVIOR OF DEVICES AND WILL ACQUIRE FAMILIARITY WITH THE MOST USED THEORETICAL APPROACHES FOR ELECTRICAL TRANSPORT AT THE NANOSCALE. THE STUDENT WILL BE ABLE TO UNDERSTAND THE SPECIALIST SCIENTIFIC LITERATURE OF THE SECTOR. INDEPENDENCE OF JUDGMENT THE STUDENT WILL BE ABLE TO IDENTIFY THE MOST APPROPRIATE PARAMETERS AND METHODS FOR THE CHARACTERIZATION OF AN ELECTRONIC DEVICE. THE STUDENT WILL ALSO BE ABLE TO USE THE BAND MODEL TO DESCRIBE THE OPTOELECTRONIC PHENOMENA THAT OCCUR IN DIODES AND TRANSISTORS AT THE MICRO-AND NANO-SCALE. WILL BE ABLE TO JUDGE THE PLAUSIBILITY AND ACCURACY OF MODELS PROPOSED TO EXPLAIN EXPERIMENTAL OBSERVATIONS. COMMUNICATION SKILLS THE STUDENT WILL BE ABLE TO EXPLAIN IN A CLEAR WAY AND WITH PROPER LANGUAGE THE OPERATION OF AN ELECTRONIC DEVICE AND THE PHYSICAL PHENOMENA THAT ARE UNDERLYING IT. LEARNING ABILITY THE STUDENT WILL BE ABLE TO APPLY THE KNOWLEDGE ACQUIRED TO UNDERSTAND THE OPERATION OF OPTOELECTRONIC DEVICES NOT PRESENTED DURING THE COURSE. ALSO, YOU WILL BE ABLE TO EVALUATE OR PROPOSE MODELS TO EXPLAIN NEW EXPERIMENTAL OBSERVATIONS. |

Teaching Methods | |
---|---|
THE COURSE INCLUDES THEORETICAL LESSONS AND APPLICATION EXAMPLES. EXERCISES WILL BE PROPOSED TO CONSOLIDATE THE LEARNING OF BASIC CONCEPTS AND TO FAMILIARIZE THE STUDENT WITH THE SITUATIONS IN PLAY. IF OF INTEREST, A PART OF THE LABORATORY DEDICATED TO THE USE OF MEASUREMENT INSTRUMENTS AND TECHNIQUES OPTIMIZED FOR NANODEVICES CAN ALSO BE INCLUDED. |
Verification of learning | |
---|---|
THE VERIFICATION OF LEARNING REQUIRES AN ORAL TEST LASTING ABOUT AN HOUR. THE ORAL EXAM FOCUS ON A SUBSET OF RANDOMLY CHOSEN COURSE TOPICS AND HAS THE PURPOSE OF DEEPENING THE LEVEL OF THEORETICAL KNOWLEDGE, THE AUTONOMY OF ANALYSIS AND JUDGMENT, AS WELL AS THE EXPRESSION ABILITY OF THE STUDENT. THE LEVEL OF ASSESSMENT TAKES INTO ACCOUNT THE EFFICIENCY OF THE METHODS USED, THE COMPLETENESS AND ACCURACY OF THE ANSWERS, AS WELL AS THE CLARITY OF THE PRESENTATION. THE MINIMUM EVALUATION LEVEL (18) IS ASSIGNED WHEN THE STUDENT DEMONSTRATES SUFFICIENT KNOWLEDGE OF THE OPERATION OF THE VARIOUS DEVICES COVERED, BUT PRESENTS SOME INACCURACIES OR INCOMPLETENESS IN THE EXPOSITION OR MATHEMATICAL FORMULATION OF THE DISCUSSED PHENOMENA. THE MAXIMUM LEVEL (30) IS AWARDED WHEN THE STUDENT DEMONSTRATES A COMPLETE AND DEEP KNOWLEDGE OF THE PHYSICS OF THE DEVICES AND IS ABLE TO FORMALIZE IT ANALYTICALLY. THE FINAL MARK, EXPRESSED IN THIRTIETH WITH POSSIBLE HONORS, IS OBTAINED BY TAKING ACCOUNT OF THE ORAL EXAM AND A SMALL PART OF THE ATTENDANCE OF THE COURSE. PRAISE IS AWARDED WHEN THE CANDIDATE DEMONSTRATES SIGNIFICANT MASTERY OF THEORETICAL AND APPLICATIONAL CONTENTS AND SHOWS THE ABILITY TO PRESENT THE TOPICS WITH REMARKABLE LANGUAGE PROPERTY AND INDEPENDENT PROCESSING ABILITY EVEN IN CONTEXTS DIFFERENT FROM THOSE PROPOSED BY THE TEACHER. |
