Abstract

Among the several purposes of the LabVIEW programming language, one of the most important is the possibility of integrating various equipment in a physics laboratory for taking data and control external parameters in an automated fashion. This type of integration allows the realization of complex and integrated experiments between multiple devices for as long as necessary, without necessarily the investigator being present. These features optimize the working time significantly and, therefore, have become an essential tool in all kinds of experiments. This project is dedicated to automation of opto-electronic experiments in the experimental facilities of the Semiconductor Nanostructure Group at UFSCar. The integration will occur with the control of the magnetic field generated inside an ultra-low vibration helium closed cycle cryostat, with the transport and optical measurements conducted with the use of a confocal microscope. Both experiments will be integrated with spectrometers and light detectors to perform luminescence experiments in continuous and pulsed waves as well as Raman spectroscopy, with or without simultaneous transport measurements, as a function of the applied magnetic field and temperature. Certainly, this automation will allow all users in the facilities to carry out experiments more efficiently, getting results in the shortest period of time possible. (AU)
