Chemical Interface Damping Depends on Electrons Reaching the Surface.

ACS Nano, 2017
Metallic nanoparticles show extraordinary strong light absorption near their plasmon resonance, orders of magnitude larger compared to nonmetallic nanoparticles. This "antenna" effect has recently been exploited to transfer electrons into empty states of

Plasma Losses by Fast Electrons in Thin Films

, 1957
The angle-energy distribution of a fast electron losing energy to the conduction electrons in a thick metallic foil has been derived assuming that the conduction electrons constitute a Fermi-Dirac gas and that the fast electron undergoes only small ...

INDIRECT EXCHANGE COUPLING OF NUCLEAR MAGNETIC MOMENTS BY CONDUCTION ELECTRONS

, 1954
A calculation is given of the indirect exchange ${\mathrm{I}}_{i}\ifmmode\cdot\else\textperiodcentered\fi{}{\mathrm{I}}_{j}$ type coupling of nuclear magnetic moments in a metal by means of the hyperfine interaction with the conduction electrons.

Anchoring semiconductor and metal nanoparticles on a two-dimensional catalyst mat. Storing and shuttling electrons with reduced graphene oxide.

Nano letters (Print), 2010
Using reduced graphene oxide (RGO) as a two-dimensional support, we have succeeded in selective anchoring of semiconductor and metal nanoparticles at separate sites.

Motion of Electrons and Holes in Perturbed Periodic Fields

, 1955
A new method of developing an "effective-mass" equation for electrons moving in a perturbed periodic structure is discussed. This method is particularly adapted to such problems as arise in connection with impurity states and cyclotron resonance in ...

The Penetration of a Potential Barrier by Electrons

, 1930
A potential barrier of the kind studied by Fowler and others may be represented by the analytic function V (Eq. (1)). The Schrodinger equation associated to this potential is soluble in terms of hypergeometric functions, and the coefficient of reflection

A survey of low-energy electrons in the evening sector of the magnetosphere with OGO 1 and OGO 3.

, 1968
Observations of electrons of energy 125 ev to ∼2 kev with the OGO 1 satellite and of electrons of energy 40 ev to ∼2 kev with OGO 3 (by means of modulated Faraday cup detectors) are used to investigate the low-energy electron population in the ...
