Hot Electrons and Hot Plasmons for Photovoltaics
Hot Electrons and Hot Plasmons for Photovoltaics David J. Norris Optical Materials Engineering Laboratory, ETH Zürich We will discuss two recently observed phenomena with implications for photovoltaic devices. First, it is well known that conventional silicon solar cells lose a significant fraction of their absorbed energy when electrons that are excited high into the conduction band cool to th...
متن کاملTheory of High-Field Transport of Hot Electrons in Semiconductors: Nonequilibrium Ensemble Method
An ever increasing degree of miniaturization of electronic devices demands an improved understanding of nonlinear transport processes of charged carriers in semiconductors subjected to large potential gradients [1–3]. Since the nonlinear transport properties of charged carriers are poorly understood in general, the problem of understanding them in the context of small systems (e.g., electronic ...
متن کاملIon acceleration by hot electrons in microclusters
A self-consistent analytical description is presented for collisionless expansion of a fully ionized cluster with a two-component electron distribution. The problem is solved for an initial “water-bag” distribution of hot electrons with no angular momentum, which reflects the mechanism of electron heating. This distribution evolves in time due to adiabatic cooling of hot electrons. The solution...
متن کاملHot electrons in low-dimensional phonon systems
A simple bulk model of electron-phonon coupling in metals has been partially successful in explaining experiments on metal films that actually involve surfaceor other low-dimensional phonons. However, by an exact application of this standard model to a semi-infinite substrate with a free surface, making use of the actual vibrational modes of the substrate, we show that such agreement is fortuit...
متن کاملA symmetric theory of electrons and positrons(∗)
— It is shown that it is possible to achieve complete formal symmetrization in the electron and proton quantum theory by means of a new quantization process. The meaning of Dirac equations is somewhat modified and there is no longer any reason to speak of negative-energy states nor to assume, for any other types of particles, especially neutral ones, the existence of antiparticles, correspondin...
