The photophysics and photochemistry of all-trans-α,ω-di(2-thienyl)polyenes (with chain length n = 2, 3, 4) and α,ω-di(3-thienyl)polyenes (with n = 3, 4) have been extensively studied by stationary and pulsed spectrometry. Fluorometric and laser f

The effect of the ambient conditions in the growth chamber of the molecular beam epitaxy machine during the growth of GaAs/Al0.35Ga0.65As structures was investigated. Both growth‐interrupted (120 s at each heterointerface) and uninterrupted surface

VDJ genes were cloned from leukemic B cells of an a1/a2 heterozygous Emu-cmyc transgenic rabbit. Restriction mapping and nucleotide sequence analysis indicated that one clone, 5C3, had a VHa1-encoding gene segment functionally rearranged to a JH gene

We have imaged for the first time the atomic structure of a quasicrystal using a scanning tunneling microscope. The structure of the decagonal ${\mathrm{Al}}_{65}$${\mathrm{Co}}_{20}$${\mathrm{Cu}}_{15}$ quasicrystal is described by a pentagon-center

The scanning tunneling microscope (STM) is used to study the clean surface of Ge(111)‐1×1:As. The surface is found to consist of hexagonal incommensurate 1×1 domains having a lateral extent of ∼ 150 A. The domain boundaries are determined to be

Vacuum scanning tunneling microscopy has been used to investigate the hydrogen‐terminated Si(111) surfaces obtained upon dissolution of the native oxide in HF and NH4F solutions. Whereas etching in aqueous HF acid produces an atomically rough surfa

Single GaAs/AlxGa1−xAs quantum wells, grown by molecular beam epitaxy with growth interruptions at each interface, are investigated using low‐temperature photoluminescence. The three clearly resolved photoluminescence peaks are attributed to disc

The larger photobiological activity of visnagin (VI) versus khellin (KH) toward several living organisms, including fungi, viruses, yeasts and bacteria, induced a detailed investigation of the photophysical properties of these naturally occurring fur

Publisher Summary This chapter discusses that the atomistic viewpoint of the vacuum tunneling microscope is a powerful tool for the examination of structures and processes on the scale of atoms. In barely ten years of existence allocated to the scann
