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

WSe2-contact metal interface chemistry and band alignment under high vacuum and ultra high vacuum deposition conditions
Christopher M. Smyth,Rafik Addou,Stephen McDonnell,Stephen McDonnell,Christopher L. Hinkle,Robert M. Wallace +5 more
TL;DR: In this article, contact metals (Au, Ir, and Cr) are deposited on bulk WSe2 under UHV and HV conditions and subsequently characterized with x-ray photoelectron spectroscopy (XPS) to elucidate the effects of reactor base pressure on resulting interface chemistry and band alignment.

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.
