NaCl single crystal

The spectroscopy of CO on NaCl single crystals has been investigated in detail by Ewing et al. (49,130-132,297-299) and Heidberg et al. (48,300,301). The structure of CO on NaCl(001) was also investigated by means of helium scattering (302, 303) and fluorescence spectroscopy (304) thermodynamic investigations (305, 306) were also reported. 

The measurements were performed on a sample consisting of polystyrene (PS) and polymethylmethacrylate (PMMA). After depositing a melt droplet of each polymer on the freshly cleaved surface of an NaCl single crystal and...

The curves I y) show the spectra displayed on the oscilloscope screen for the different paths travelled by the movable mirror indicated in the interferogram. These data were obtained with a Poly tec FIR 30 Fourier spectrometer...

Studying chemical effects of ion implantation of S into single crystal NaCl, it was found that the same chemical species S , S measured as CNS, SOs , and S04 were formed as those in Cl(n,p) S reaction in NaCl, but their percentages showed a little difference. Implantation angles to the crystal axis affected the chemical fate of in NaCl single crystals...

The phase transition and microstmcture of as-deposited B-Fe, B-Co and B-Co-Fe alloy films on copper, mica, glass and NaCl single crystals were examined using differential scanning calorimetry and transmission electron microscopy by [1986Cha]. The microstracture appears to be either in the amorphous state or partially crystallized, depending on the composition of flie films.

Calculations of this type are carried out for fee, bcc, rock salt, and hep crystal structures and applied to precursor decay in single-crystal copper, tungsten, NaCl, and LiF [17]. The calculations show that the initial mobile dislocation densities necessary to obtain the measured rapid precursor decay in all cases are two or three orders of magnitude greater than initially present in the crystals. Herrmann et al. [18] show how dislocation multiplication combined with nonlinear elastic response can give some explanation for this effect. 

A series of Be-Pt intermetallic compounds arc prepared during the electrodeposition of Be on Pt from a solution of BeCl2 in an equimol NaCl-KCl mixture at 710°C. X-Ray diffraction of the electrode surface shows the presence of BePt, BcjPt. Electrolytic methods are also used to extract single crystals of Be,V from alloys prepared by arc melting Be and the transition metal in the proportion 15 1. 

The UPD of Zn + on Au(lll), Au(lOO), and Au(llO) was studied in phosphate buffer with addition of NaCl04 and NaCl [200]. The apparent number of electrons transferred in the UPD process was nearly one, irrespective of the single-crystal face. Although UPD shift potential ATp was independent of the kind of solutions, the CV characteristics were altered in different solutions. In NaCl solutions, two UPD peaks appeared in contrast to the case of phosphate and perchlorate solutions.

Within these three categories, the earliest attention was paid to point defects this arose from intellectual curiosity about the origin of the deep blue color seen in large colorless single crystals of NaCl occurring in salt deposits. From this starting point, the idea of color centers was developed. Since the color centers are point defects, they modify the electronic states around the defects and affect the heat and electronic conductivity consequently, they have become directly connected to the development of the semiconductor industry.
