where e is the electron charge, and ϵ is the dielectric permittivity of the material. • Excitons are fundamental electronic excitations associated to bound states of e-h pairs acting as a hydrogen-like atom. The exciton binding energy is given by: (31)Eb=μm0ε02ε2Ryn2n=123… wher...

This treatment uses the formula for the ground-state ionization energy of a hydrogen atom including a simple Coulomb potential, but in which the vacuum permittivityε0 is replaced by KSε0, where KS is the dielectric constant of the semiconductor and the fundamental electron mass m0 is replaced...
The electron mass in atomic mass units has been determined with a relative uncertainty of 2.8 x 10(-11) (Sturm et al 2014 Nature 506 467-70), which represents a 13-fold improvement of the 2010 CODATA value (Mohr et al 2012 Rev. Mod. Phys. 84 1527-605). The underlying measurement ...
Electron, lightest stable subatomic particle known. It carries a negative charge of 1.6 x 10^-19 coulomb, which is considered the basic unit of electric charge. The electron was discovered in 1897 by the English physicist J.J. Thomson during investigatio
The hydrogen, carbon, nitrogen and oxygen composition of the tumor samples was determined. Photon mass energy-absorption data in the energy range 1 keV to 20 MeV have been calculated using elemental mass energy-absorption coefficients previously calculated by Hubbell and Seltzer. Electron mass ...
Neutron, neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinary hydrogen (whose nucleus has one proton and no neutrons). Along with protons and electrons, it is one of the three basic particles ma
The rapid and uncontrolled fusion of deuterium nuclei is the basis of the ‘hydrogen bomb’ and nuclear fusion processes are responsible for the evolution of energy from the sun, but so far it has not been possible to produce a controlled fusion process on earth with an overall energy release...
