Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American physicist who received the Nobel Prize in Physics in 1923 for the measurement of the elementary charge and for his work on the photoelectric effect.
In 1914, Robert A. Millikan's highly accurate measurements of the Planck constant from the photoelectric effect supported Einstein's model, even though a corpuscular theory of light was for Millikan, at the time, "quite unthinkable". [45]
1916 - Robert Millikan conducts experiments and proves the photoelectric effect. 1918 - Jan Czochralski produces a method to grow single crystals of metal. Decades later, the method is adapted to produce single-crystal silicon. 1921 - Einstein awarded the Nobel Prize in Physics for his work on the photoelectric effect.
The photoelectric effect: Einstein explained this in 1905 (and later received a Nobel prize for it) using the concept of photons, particles of light with quantized energy. Robert Millikan's oil-drop experiment, which showed that electric charge occurs as quanta (whole units). (1909)
1913 Robert Millikan measures the fundamental unit of electric charge; 1913 William Henry Bragg and William Lawrence Bragg work out the Bragg condition for strong X-ray reflection; 1914 Ernest Rutherford suggests that the positively charged atomic nucleus contains protons [4] 1914 James Franck and Gustav Hertz observe atomic excitation
While at General Electric, he began to research the photoelectric effect, which causes matter to emit electrons when exposed to some types of electromagnetic radiation.In 1916 Robert Andrews Millikan, while verifying the photoelectric equations of Albert Einstein, had proposed the idea that photoelectrons emitted from semiconductors should behave in a different way than those emitted from ...
Robert Andrews Millikan publishes the results of his "oil drop" experiment, in which he precisely determines the electric charge of the electron. Determination of the fundamental unit of electric charge makes it possible to calculate the Avogadro constant (which is the number of atoms or molecules in one mole of any substance) and thereby to ...
