Local‐field effects and effective‐medium theory: A microscopic perspective
- D. E. Aspnes
- Physics
- 1 August 1982
Standard textbook derivations of the Clausius–Mossotti (Lorentz–Lorenz) relation tend to obscure the physical origin of local‐field effects by proceeding from the macroscopic dielectric function of… Expand
Static Phenomena Near Critical Points: Theory and Experiment
- L. Kadanoff, W. Götze, +7 authors J. W. Kane
- Physics
- 1 April 1967
Expanding horizons: new developments in ellipsometry and polarimetry
- D. E. Aspnes
- Chemistry
- 1 May 2004
This is the eighth in the aperiodic series of ellipsometry conferences, and the third devoted specifically to spectroscopic ellipsometry. I discuss the evolution of the field mainly from a… Expand
Analytic representations of the dielectric functions of materials for device and structural modeling
- J. Leng, J. Opsal, Hanyou Chu, M. Senko, D. E. Aspnes
- Materials Science
- 13 February 1998
Abstract Analytic representations of the dielectric function e are needed for the analysis of optical data of complex materials and structures. Here, we examine various harmonic-oscillator-based… Expand
Plasmonics and effective-medium theories
- D. E. Aspnes
- Materials Science
- 28 February 2011
The field of plasmonics has recently undergone a renaissance with the development of methods that can systematically produce structures on submicron scales. Plasmons, plasmon polaritons, and… Expand
Schottky-barrier electroreflectance of Ge: Nondegenerate and orbitally degenerate critical points
- D. E. Aspnes
- Physics
- 15 September 1975
Critical-point energies, broadening parameters, line-shape asymmetries, interband reduced masses, and polarization anisotropies are measured for the ${E}_{0}$, ${E}_{0}+{\ensuremath{\Delta}}_{0}$,… Expand
Simplified bond-hyperpolarizability model of second harmonic generation
- G. D. Powell, J. Wang, D. E. Aspnes
- Physics
- 17 May 2002
We show that the anisotropies of second-harmonic-generation (SHG) intensities of vicinal (111) and (001)Si-SiO 2 interfaces can he described accurately as dipole radiation originating from the… Expand
Bounds on allowed values of the effective dielectric function of two-component composites at finite frequencies
- D. E. Aspnes

Dielectric functions and interband transitions of InxAl1 - xP alloys
- T. Kim, S. Y. Hwang, +11 authors Y. Kim
- Materials Science
- 1 September 2014
Abstract We report pseudodielectric functions from 1.5 to 6.0 eV of InxAl1 − xP ternary alloy films. Data were obtained by spectroscopic ellipsometry on 1.2 μm thick films grown on (001) GaAs… Expand
Systematic differences among nominal reference dielectric function spectra for crystalline Si as determined by spectroscopic ellipsometry
- K. A. Bell, L. Mantese, U. Rossow, D. E. Aspnes
- Materials Science
- 13 February 1998
Abstract Results of the first systematic investigation of differences among reference-quality ellipsometrically measured pseudodielectric function 〈e〉 spectra of crystalline Si are discussed. These… Expand
