Objectives
THE COURSE WIDENS THE KNOWLEDGE REGARDING ELECTRONIC TRANSPORT IN SEMICONDUCTORS INTRODUCING THE CONCEPTS OF HETEROJUNCTIONS AND QUANTUM STRUCTURES AND INTRODUCES ADDITIONALLY THE OPTICAL PROPERTIES OF A SERIES OF SEMICONDUCTOR MATERIALS.THE PRINCIPAL OPTOELECTRONIC DEVICES ARE INTRODUCED AND TYPICAL APPLICATIONS FOR THESE DEVICES ARE DEMONSTRATED.

AT THE END OF THE COURSE, THE STUDENT:
KNOWS THE PRINCIPAL INTERACTIONS BETWEEN LIGHT AND MATTER.
KNOWS THE MOST IMPORTANT MATERIALS FOR OPTOELECTRONIC APPLICATIONS.
UNDERSTANDS THE WORKING PRINCIPLES OF THE FUNDAMENTAL OPTOELECTRONIC DEVICES.

LEARNED TO CHOOSE THE APPROPRIATE MATERIALS AND DEVICES FOR FINALIZING PROJECTS IN OPTOELECTRONICS AND PHOTOVOLTAICS.

LEARNED HOW TO EXTRACT IMPORTANT PARAMETERS OF OPTELECTRONIC DEVICES FROM MEASUREMENTS, PERFORMED DURING THE LABORATORY EXERCISES.

DEVELOPED SIMPLE APPLICATIONS OF OPTOELECTRONIC DEVICE, FOR EXAMPLE IN THE FIELD OF OPTICAL SENSORS AND OPTICAL FIBER BASED DATA TRANSMISSION SYSTEMS.

IS ABLE TO CHARACTERIZE SOLAR CELLS AND PANELS AND EXTRACT THE MOST IMPORTANT PARAMETERS.

LEARNED HOW TO DEVELOP, REALIZE AND TEST A SIMPLE PHOTOVOLTAIC SYSTEM.

COMMUNICATION SKILLS:
BEING ABLE TO DESCRIBE, IN WRITTEN AND ORAL FORM, CORRECTLY AND CLEARLY THE ACQUIRED KNOWLEDGE, AND TO PRODUCE DOCUMENTS, DESCRIBING THE LABORATORY EXPERIENCES.

LEARNING SKILLS:
THE STUDENT WILL BE ABLE TO DEEPEN THE TOPICS PRESENTED IN THE COURSE BY USING MULTIPLE SOURCES AND MATERIALS.

Teaching Methods
THE COURSE CONSISTS OF THEORETICAL LESSONS (60H), CLASSROOM EXERCISES (9H) AND LABORATORY EXERCISES (21H).


Verification of learning
THE ACHIEVEMENT OF THE OBJECTIVES OF THE TEACHING IS CERTIFIED BY THE SUCCESSFUL PARTECIPATION OF AN EXAMINATION WITH MAXIMUM 30 POINTS (THE MINIMUM LEVEL OF SURFACING CORRESPONDS TO "18" AND THE MAXIMUM TO "30 AND LODE"), WHICH PROVIDES A SINGLE ORAL TEST OF DURATION INDICATIVE LASTING ABOUT 30 MINUTES, AND FINALIZED TO VERIFY: 1) THE LEARNING OF ARGUMENTS TREATED IN THE HOURS OF FRONTAL TEACHING; 2) THE CONTRIBUTION TO THE GROUP PROJECT REALIZED ON A TOPIC ASSIGNED BY THE PROFESSOR; 3) THE EXPOSURE CAPACITY OF THE TOPICS CONTAINED; 4) THE AUTONOMY OF JUDGMENT IN PROPOSING THE SOLUTION TO A GIVEN OPTOELECTRONIC DESIGN PROBLEM.
MORE IN DETAIL, THE ORAL TEST PROVIDES THREE QUESTIONS: THE FIRST CONCERNING THE REALIZED PROJECT AND THE OTHER TWO CONCERNING THE TOPICS DURING THE FRONTAL TEACHING: IN GENERAL ONE IN THE FIELD OF OPTOELECTRONICS AND THE OTHER ONE IN THE FIELD OF PHOTOVOLTAICS.
DURING THE COURSE, PARTIAL “INTRA-CORSO” TESTS ARE PROVIDED.
TO PASS THE EXAM IT IS NECESSARY TO REACH SUFFICIENCY BOTH IN THE VERIFICATION OF THE LEARNING OF ARGUMENTS TREATED AND IN THE VERIFICATION OF THE ASSIGNED LABORATORY PROJECT.
THE STUDENT REACHES THE LEVEL OF EXCELLENCE IF THE REALIZED PROJECT PRESENTS INNOVATIVE SOLUTIONS AND DURING THE ORAL TEST THE FULL KNOWLEDGE OF THE TOPICS ON WHICH HE OR SHE HAS BEEN QUESTED IS DEMONSTRATED.
