Development of a New Lecture/Lab Course on Quantum Mechanics for Engineering Students Vladimir Mitin, Nizami Vagidov, Xiufeng Liu, and Athos Petrou University at Buffalo, The State University of New York, Buffalo, NY 14260-1920A new combined lecture/lab course on quantum mechanics EE 418/518 “Quantum Mechanicsfor Engineers” for University at Buffalo (UB) engineering students has been developed under thesupport of NSF grant “DUE-0837670, CCLI: First course in nanoelectronics for engineers”.The lecture part of this course has been developed and pilot tested at UB in Fall 2009 semester.During Fall 2010 the combined course is taught for the first time. The textbook “QuantumMechanics for Nanostructures” by V. Mitin, D. Sementsov, and N. Vagidov was developed forthe course and published by Cambridge University Press just before the Fall 2010 semester. Theemphasis in the course is placed on the learning of quantum-mechanical concepts by consideringnanostructures as examples of microscopic objects. These structures are used in a large numberof modern electronic devices. As part of the lab, the students will explore some of thenanostructures discussed in lectures. This significantly improves the understanding of quantummechanical concepts and principles which define the operation of nanostructure devices.In order to evaluate engineering students’ understanding of quantum-mechanical concepts, twomultiple-choice paper-pencil tests, one as pre-test and another as post-test, have been developed.The pre-test contains 15 lower difficulty questions and has been given at the beginning of thesemester. The pre-test assesses the students’ knowledge of quantum-mechanical concepts priortaking the course. The post-test, which contains 40 questions of varying difficulty and includesthe 15 questions from the pre-test, will be given at the end of this semester. The test will assessthe students’ progress in understanding of quantum-mechanical concepts. Assessment andevaluation plan also includes two survey forms: “Survey of Students’ Interest toward QuantumMechanics (SSIQM)” and “Evaluation of Effectiveness of Quantum Mechanics CourseMaterials”. In order to evaluate students’ ability to solve experimentally quantum-mechanicalproblems, 1.5 month before the end of the semester, students will be asked to solve a specificproblem in pairs. The above-mentioned instruments will be given to students for multiple yearsto validate the instruments.The lab part of the course that will help students to comprehend quantum-mechanical conceptsincludes nine experiments that were newly developed. In particular:Photoelectric effect: waves behaving as particles. Carrying out this lab students explore thephotoelectric effect and determine the value of Planck’s constant.Study of InAs quantum dots using atomic force microscope (AFM). The students use atomic forcemicroscope to determine the sizes and shapes of InAs quantum dots grown on semiconductorsubstrates.Interband transitions between conduction and valence confinement subbands in GaAs/AlGaAsquantum wells. Students become familiar with the technique of reflectivity and apply it for thestudy of interband transitions between the conduction and valence subbands in GaAs/AlGaAsquantum wells.
