... with a crystalline substance ( Thomson and Reid, 1927 ). There seemed to be a world of mystery surrounding spectroscopy—light interacting with matter. There were four experiments that Newtonian physics could not explain. Hydrogen (and other atoms) emitted discrete spectral lines when excited. The emission...

... incumbent wide bandgap semiconductors such as GaN. This chapter reviews the status of high-energy ionizing and nonionizing radiation studies on β-Ga₂O₃ with a focus on characterizing the radiation-induced defects formed using quantitative defect spectroscopy techniques. The potential...

... that Newtonian physics could not explain: The emission spectrum of a hot object (blackbody radiation) depended upon temperature and not on the identity of the substance. Hydrogen (and other atoms) emitted discrete spectral lines when excited. Photoelectrons streamed off a surface with a kinetic energy...

... is where the wave functions of the quantum system first appear. Schrödinger called this integral the total electronic moment. For absorption and stimulated emission ( I n → n ′ a ) this integral is calculated using the dipole approximation, named after the dipole in the atom...

... of real-life spectroscopy and quantum mechanics. Wave functions, energy equations, transition intensities, and spectroscopic selection rules for absorption, emission, Rayleigh, and Raman spectra are derived and applied to explore why the sky is blue, why sunsets are red, and how quantum effects depend...

...Absorption Stick Spectrum for the 1DPB System To plot the absorbance stick spectrum for a 1DPB system, we must pull all the prior results together so that we can see the big picture in detail. In Chap. 2, we established the equations related to absorption spectroscopy where the overall absorption...

... and are an easy application of second-semester calculus. Larger systems up to the hydrogen atom and the molecular hydrogen cation have been solved analytically, but these mathematical solutions are highly complex. Even Schrödinger exclaimed in a letter to his colleague, “If only I knew more math!” and he...

... of 2D materials enables us to utilize photoluminescence and UV–visible absorption spectroscopy to determine the thickness of thin atomic sheets of 2D materials. UV-Vis absorption and PL emission can directly probe the electronic properties of materials as absorption and emission are intricately related...

.... The CV extracted FWHM of an ideal delta sheet will be close to z₀. SIMS (secondary-ion mass spectroscopy) and CV measurements are commonly used to determine the abruptness of delta-doped channels. Depending on the effective mass and donor atom density, the carriers can occupy multiple...

Material sensing is often performed by spectroscopy (absorption, emission, or transmission) using acoustic to electromagnetic vibrations spanning a wide range of frequencies. A spectrometer consists...

... the correlation between frequency and atomic number, which has become the fundamental concept behind contemporary x-ray spectroscopy. The development of detector technology in the 1940s helped XRF analysis become a more practical tool. Finally in 1970 the first commercial XRF instrument based on a lithium-drifted...
