This study details the formulation of experimental materials pertaining to semiconductors and their subsequent implementation among international students. The experimental documentation titled "Exploring the inside of a pn junction diode" conducted at the Department of Electronics and Information Engineering, National Institute of Technology, Ishikawa College, has been translated into English. Notably, the refinement of the experimental apparatus has resulted in a more streamlined version compared to its predecessor. Additionally, this investigation addressed the maintenance of a constant temperature within the thermostatic chamber encompassing the diode because of the time-intensive nature of temperature control. Three graduate students from Universiti Teknologi Mara,Malaysia, actively participated in the prepared experiment and subsequently provided feedback through a questionnaire. One noteworthy suggestion emerged from this feedback, proposing that the comprehension of this experiment could be enhanced if video demonstration were to accompany the instructional material.
