Planck constant is a fundamental concept in physical sciences,and Millikan received the Noble Prize for determining it experimentallyin 1923. As the technology of solid state electronicdevices developed, an experiment was designed andadapted to determine the Planck’s constant using LED [1,2]. Herrmann and Sch¨atzle  questioned the validity of thisexperiment on the basis of the diode equation, and their approachwas further discussed by Morehouse . In this article,the validity of this experiment is revisited.

De Broglie’s hypothesis of the dual nature of matter was conﬁrmed experimentally independently by Davisson-Germer and G. P. Thomson. But most of the textbooks (e.g. ) discuss Davisson–Germer experiment. In this article, G. P. Thomson’s experiment of electron diﬀraction is discussed.
