Surface form errors generated by process variation in optical lens fabrication are optimally described using polynomial representations that are orthogonal, physically relevant, and result in small model fitting residuals. Similarly, discrete vector

Multivariate factor analysis of X-ray photoelectron spectroscopy data acquired from Athabasca oil sands heavy minerals concentrate was used to identify the primary mineral components and their physical associations. Using large-area spectroscopy, a p

The photonic stability of sulfurized GaAs(001) exposed to phosphate buffered saline (PBS) solution was investigated by in situ photoluminescence (PL). Results show that samples first coated with hexadecanethiol (HDT) self- assembled monolayers (SAMs)

Properties of as prepared or nanoengineered III–V semiconductor surfaces provide attractive means for photonic detection of different adsorbants from surrounding gaseous or liquid environments. To be practical, this approach requires that the surfa
The electro-optic characteristics of the semi-insulating and n + -type GaAs(001) surfaces passivated with n-alkanethiol self-assembled monolayers were investigated using Kelvin probe surface photovoltage (SPV) and photoluminescence (PL) techniques. R

The surface Fermi level of semi-insulating and n + -type GaAs(0 0 1) was determined before and after passivation with n -alkanethiol self-assembled monolayers (SAMs) by X-ray photoelectron spectroscopy. Fermi level positioning was achieved using Au c

The work function of n-alkanethiol self-assembled monolayers (SAMs) prepared on the GaAs(001) surface was measured using the Kelvin probe technique yielding the SAM 2D dipole layer potential (DLP). Direct n-dependent proportionality between the DLP v
Alkanethiol self-assembled monolayers (SAMs) of various methylene group chain lengths [HS–(CH₂)n–CH₃] (n=9,11,13,15,17) were fabricated on the GaAs(001) surface followed by characterization using Fourier transform infrared spectroscopy. Modal
