Average Course Rating

(3.9)

This laboratory concentrates on the experimental investigation of electronic properties of materials using basic measurement techniques. Topics include thermal conductivity of metal alloys, electrical conductivity of metals/metal alloys and semiconductors, electronic behavior at infrared wavelengths, magnetic behavior of materials, carrier mobility in semiconductors and the Hall effect in metals and semiconductors. Lab Assignment is by Professor. Recommended Course Background: EN.510.311 or Permission Required.

The best aspects of this course included the helpful lab write-ups and the professor. The worst aspects of the course included the defective lab equipment, unorganized labs, and unclear lab reports. The students found the labs confusing and vague, which affected how they col ected data and did some experiments. The course would improve if the lab designs were better structured with better equipment. Prospective students should endeavor to start their lab reports on time because it involves lots of data analysis.

During this course, the application of principles learned in previous classes was experienced by students. Through labs, students were given a basic idea of electrical properties of materials. Many students raved about the transistor lab because they were able to use their knowledge of electricity and magnetism to complete it. Also, the professor was very kind and cared about her students. The worst aspects of this course were the lab reports, the labs being done in groups, and repetitive assignments. Suggestions for improvement include: clearer lab guidelines, more theory discussion, and some degree of individual assessment. Prospective students should be able to stay on top of their reports.

The best aspects of the course included the professor and the ability to apply the theories and equations learned in class in a hands-on lab environment. Students very much enjoyed the experiments and the familiarity they developed with a variety of devices and materials. Some students agreed that the course was unorganized at times, and that there were equipment failures on several occasions that made conducting the experiments difficult. Better organization and structure to the labs would have al owed for a more efficient use of time. Prospective students should be prepared to do more writing than expected, and to start Arduino projects as early as possible.
