TLDR
In this paper, the fundamental problems of the electronic band structure and the lattice vibration spectrum of particles having only 102 to 104 atoms are still in the beginning theoretical stages and various anomalies should occur if the mean electronic level spacing exceeds thermal or photon or magnetic excitations.Abstract:
Changes in several solid state properties are expected when moving from the bulk crystal to small particles. The fundamental problems of the electronic band structure and the lattice vibration spectrum of particles having only 102 to 104 atoms are still in the beginning theoretical stages. Various anomalies should occur if the mean electronic level spacing exceeds thermal or photon or magnetic excitations. The recent widespread interest on surface excitations (surface phonons and plasmons) in small particles arises from the possibilities of observing the effects with infrared absorption and Raman and neutron scattering.read more

Metal colloids in ionic crystals
A.E. Hughes,S.C. Jain +1 more
TL;DR: In this article, a review discusses the progress which has been made through the use of a large number of different techniques to study the properties of small metallic particles. But the results of these studies are limited.

Evolution of the optical functions of thin-film aluminum: A real-time spectroscopic ellipsometry study
TL;DR: This study relies on ellipsometric spectra from 1.3 to 4.0 eV collected in real time with a multichannel instrument during both thermal evaporation and magnetron sputtering of Al onto SiO 2 substrates at room temperature.

On the computation of optical properties of heterogeneous grains
TL;DR: In this paper, the authors derived the effective dielectric function of a composite medium consisting of small spherical inclusions embedded in a homogeneous matrix and showed that the validity of the theory does not depend on the matrix being nonabsorbing.

Simultaneous real‐time spectroscopic ellipsometry and reflectance for monitoring thin‐film preparation
TL;DR: In this paper, an expansion of the capabilities of high-speed, multichannel spectroscopic ellipsometry (SE) is described that involves simultaneous measurement of the reflectance spectrum along with the two spectra in the ellipsometric angles (ψ, Δ).

Dynamical Theory of Crystal Lattices
Max Born,Kʿun Huang +1 more
TL;DR: Born and Huang's classic work on the dynamics of crystal lattices was published over thirty years ago, and it remains the definitive treatment of the subject as mentioned in this paper. But it is not the most complete work on crystal lattice dynamics.

Transition temperature of strong-coupled superconductors.
TL;DR: In this paper, the superconducting transition temperature is calculated as a function of the electron-phonon and electron-electron coupling constants within the framework of strong coupling theory.

Colours in Metal Glasses and in Metallic Films
TL;DR: In this paper, it was shown that the presence of many of these minute spheres to a wave-length of light in the glass will account for all the optical properties of "regular" gold ruby glass, and that the irregularities in colour and in polarisation effects sometimes exhibited by gold glass are due to excessive distance between consecutive gold particles or to excessive size of such particles.
