Cross‐sectional scanning tunneling microscopy and spectroscopy were used to study a modulation‐doped Si/Si0.76Ge0.24(001) superlattice. Contrast between the Si and Si0.76Ge0.24 layers has been observed in topographic images. Features such as band

Potential distributions across Si(001)p‐n junctions have been studied using cross‐sectional scanning tunneling microscopy, spectroscopy, and potentiometry. A clear transition between p‐ and n‐type material can be seen across each junction, an

Scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) are used to investigate a cross‐sectional surface of Si(100) prepared by an ex situ cleave HF‐dip technique. The agreement between the measured current–voltage spectr

We describe an experimental technique for evaluating the phase-matching properties of nonlinear optical materials in powder form. The short wavelength phase-matching cutoff can be measured for new materials in a form readily available. We also select

We report measurements on the second and third order nonlinear hyperpolarizabilities of the urea molecule using the techniques of dc field induced second-harmonic generation and four-wave mixing. Single crystals of urea have been grown and found to h

The potential of sucrose crystal, which is transparent down to 190 nm, for nonlinear UV generation is investigated. Sellmeier's equations for the refractive indices of sucrose are presented. From these, the phase-matching curves for second-harmonic g
