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

Nanoscale conduction modulation in Au/Pb(Zr, Ti)O3/SrRuO3 heterostructure
TL;DR: In this article, the authors used the Au-coated cantilever of scanning probe microscopy (SPM) as a mobile top electrode in an Au-tip/Pb(Zr, Ti)O3(PZT)/SrRuO3 heterostructure.

Synchronization of femtosecond laser and electron pulses with subpicosecond precision
TL;DR: In this paper, the temporal evolution of electron shadow images, formed by the projection of primary femtosecond electron pulses (probe) over a metal target and perturbed by the transient space-charge field near the target surface induced by the excitation of femtocond optical pulses (pump), is recorded in real time.

Ionic liquid ultrathin films at the surface of Cu(100) and Au(111).
TL;DR: It is proposed that the particularly strong cation-Cu interaction leads to stabilization of the anion and prevents its decomposition at the surface of Cu(100) as well as a large interface dipole upon deposition of a monolayer of IL on Cu.

A practical demonstration of electronic promotion in the reduction of ceria coated PGM catalysts
TL;DR: When ceria is deposited over supported PGM catalysts its reducibility is dependent on the work function of the underlying metal.

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.
