New types of thermoelectric generators can work at temperatures up to 1000 K. With this, special measurement equipment is needed to control the electrical parameters of the new developed specimens. The devices must be tested over the whole range of operating temperatures. For each temperature value a series of electrical measurements has to be performed. To establish the maximal output power of the thermoelectric generators, a load resistor with variable resistance has to be connected to the output of thermoelectric generator. The measurement system should measure the electrical current through the load resistor and the voltage over this resistor to determine the device parameters. A large amount of measurement data have to be collected and processed to evaluate the electrical characteristics of the specimen and to present them in graphical form, suitable for the comparison with others specimens.","lang":"eng"}],"type":"journal_article","publication":"MRS Proceedings","language":[{"iso":"eng"}],"keyword":["General Engineering"],"user_id":"8282","department":[{"_id":"59"},{"_id":"977"}],"_id":"39514"},{"title":"Optical gain and lasing in GaNAsP/BGa(As)P heterostructures grown on (001) silicon substrate","author":[{"first_name":"Markus","last_name":"Finkeldey","full_name":"Finkeldey, Markus"},{"first_name":"Nektarios","last_name":"Koukourakis","full_name":"Koukourakis, Nektarios"},{"id":"115298","full_name":"Gerhardt, Nils Christopher","last_name":"Gerhardt","orcid":"0009-0002-5538-231X","first_name":"Nils Christopher"},{"first_name":"Martin R.","last_name":"Hofmann","full_name":"Hofmann, Martin R."},{"full_name":"Zimprich, Martin","last_name":"Zimprich","first_name":"Martin"},{"full_name":"Volz, Kerstin","last_name":"Volz","first_name":"Kerstin"},{"first_name":"Wolfgang","last_name":"Stolz","full_name":"Stolz, Wolfgang"}],"date_created":"2026-02-20T10:04:20Z","date_updated":"2026-02-25T09:33:29Z","citation":{"ieee":"M.
