Passivation of semiconductor surfaces against chemical attack can be achieved by terminating the surface-dangling bonds with a monovalent atom such as hydrogen. Such passivation invariably leads to ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

ONE of the most striking characteristics of both auroral and night-sky spectra is the absence of hydrogen lines. So far as I am aware, not even a trace of the atomic or molecular spectra of hydrogen ...
