The work function of the elements and its periodicity
TLDR
In the data for the 63 elements, trends that occur simultaneously in both the columns and the rows of the periodic table are shown to be useful in predicting correct values and also for identifying questionable data.Abstract:
A new compilation, based on a literature search for the period 1969–1976, is made of experimental data on the work function. For these 44 elements, preferred values are selected on the basis of valid experimental conditions. Older values, which are widely accepted, are given for 19 other elements on which there is no recent literature, and are so identified. In the data for the 63 elements, trends that occur simultaneously in both the columns and the rows of the periodic table are shown to be useful in predicting correct values and also for identifying questionable data. Several illustrative examples are given, including verifications of predictions published in 1950.read more

Promotion of Ceria Catalysts by Precious Metals: Changes in Nature of the Interaction under Reducing and Oxidizing Conditions

TL;DR: By depositing ceria over supported precious metal (PM) catalysts and characterizing them with in situ diffuse reflectance UV (DR UV) and in situ Raman spectroscopy, they have been able to prove a direct correlation between a decrease in ceria band gap and the work function of the metal under reducing conditions.

Epitaxial CoGa and textured CoAs contacts on Ga1-xAlxAs fabricated by molecular-beam epitaxy
TL;DR: In this paper, CoGa and CoAs have been deposited on Ga1−xAlxAs surfaces, which results in the preferential formation of two epitaxial orientations.

Investigation of the Electric Structures of Heterointerfaces in Pt- and In2S3-Modified CuInS2 Photocathodes Used for Sunlight-Induced Hydrogen Evolution
TL;DR: Spectroscopic evaluation of conduction band offsets revealed that In2S3/CuInS2 had a notch-type conductionBand offset, whereas a cliff-type offset was formed in CdS/Cu inS2, indicating the formation of a favorable heterointerface in In2 S3/ CuInS 2 for efficient charge separation.

Oxidation potentials correlate with conductivities of aromatic molecular wires.
TL;DR: Cyclic voltammetry determines first and second oxidation potentials of conducting diamines and shows that unsubstituted and methyl-substituting molecules conduct electricity in partiallyPositive situations.

Work function measurements on (100) and (110) surfaces of silver
A. W. Dweydari,C. H. B. Mee +1 more
TL;DR: In this article, the work functions of the bulk crystals and of silver films formed upon them by auto-epitaxy were determined photoelectrically, and the results support the Smoluchowski correlation of work function with surface atom density.

Work Functions of the Elements
TL;DR: The work function φ is a periodic function of atomic number, as shown clearly by a new compilation of published data for 57 elements as mentioned in this paper, and the progressive rise and fall of work function values throughout the table of the elements appears to be sufficiently regular to permit approximations to be made of values for the metallic and semimetallic elements on which no data has yet been published.

Anisotropic work function of clean and smooth low-index faces of aluminium
TL;DR: In this paper, the anisotropic work function of smooth (100), smooth (111), and (110) faces of a single crystal were cleaned through a mild cyclic treatment of ion bombardment and annealing.
