Experiments in the technology of semiconductor devices: fabrication of planar devices demonstrated by the case of a LED: fabrication steps with several masks and subsequent measurement with the fabricated device. Among the process steps are photolithography, etching, lift-off, contacting, measurement of characterisics, functional test.
Start and dates of the experiments will be fixed during the preparatory meeting. Date of the preparatory meeting will be given at StudIP after enrollment.
During the lab course Room Lighting the students apply theoretical knowledge of the lecture and class of Lighting Engineering to practical experience and discuss real lighting situations in small groups. For this the students carry out professional measurements with documentation and appraisal. Additionally, the situations will be calculated manually (point lighting, efficiency method, power consumption) as well as automatically (simulation with ray tracing). Rooms and circulation spaces of the University are chosen which are equipped with modern lighting systems (T5 flourescent tubes or LEDs). Each group will create a poster and will present the chosen lighting situation as well as the achieved results.
The lab course completes the lecture and class of the module Lighting Engineering of the Master programme towards practical experiences. Especially the comparison of measured and calculated real lighting situations gives a clear relation between theory and practice. The documentation which has to be compiled corresponds to the planing and verification of a professional installation or a certification of a lighting system. For this purpose the acquired theoretical knowledge has to be applied to practical tasks which also trains a critical view to daily lighting situations.
Prerequisite: Lecture "Lighting Engineering 1".
Start and dates of the experiments will be fixed during the planning meeting.
