Richard Phillips Feynman ( / ˈfaɪnmən /; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in ...
Physicists John Bardeen, Walter Brattain, and William Shockley developed the first transistor, a type of semiconductor, at Bell Laboratories. This breakthrough laid the groundwork for modern semiconductor technology. Silicon is the most commonly used semiconductor material.
Há 1 dia · Abstract. We observe quantum beats in the nanosecond-scale photoluminescence decay of rubrene single crystals after photoexcitation with short laser pulses in a magnetic field of 0.1 to 0.3 T. The relative amplitude of the quantum beats is of the order of 5%. Their frequency is 1.3 1.3 1.3 1.3 GHz when the magnetic field is oriented parallel to ...
