First-Principles Study of a Mos2-Pbs Van Der Waals Heterostructure Inspired by Naturally Occurring Merelaniite

Jaszczak Department of Physics, Michigan Technological University, Houghton, MI 49931, USA; [email protected] (G.D.D.); [email protected] (S.K.); [email protected] (J.A.J.) * Correspondence: [email protected] Abstract: Vertically stacked, layered van der Waals (vdW) heterostructures offer the possibility to design materials, within a range of chemistries and structures, to possess tailored properties. Inspired by the naturally occurring mineral merelaniite, this paper studies a vdW heterostructure composed of a MoS2 monolayer and a PbS bilayer, using density functional theory. A commensurate 2D heterostructure film and the corresponding 3D periodic bulk structure are compared. The results find such a heterostructure to be stable and possess p-type semiconducting characteristics. Due to the heterostructure’s weak interlayer bonding, its carrier mobility is essentially governed by the constituent layers; the hole mobility is governed by the PbS bilayer, whereas the electron mobility is governed by the MoS2 monolayer. Furthermore, we estimate the hole mobility to be relatively high (~106 cm2V−1s−1), which can be useful for ultra-fast devices at the nanoscale.

URANINITE ALTERATION IN AN OXIDIZING ENVIRONMENT AND ITS RELEVANCE TO THE DISPOSAL OF SPENT NUCLEAR FUEL Robert Finch Rodney Ewing Department of Geology University of New Mexico Submitted to Svensk Kämbränslehantering AB (SKB) December 21,1990 ABSTRACT Uraninite is a natural analogue for spent nuclear fuel because of similarities in structure (both are fluorite structure types) and chemistry (both are nominally UOJ. Effective assessment of the long-term behavior of spent fuel in a geologic repository requires a knowledge of the corrosion products produced in that environment. -

Needlelike crystals, elongated along [001], to 1 mm, in radial fibrous aggregates and crusts. Physical Properties: Tenacity: Flexible. Hardness = Soft. D(meas.) = 3.58 (synthetic). D(calc.) = 3.64 Radioactive. Optical Properties: Translucent to transparent. Color: Yellow to pale yellow; nearly colorless in transmitted light. Luster: Vitreous. Optical Class: Biaxial (+).

Characterization of naturally-occurring material thus rests on equivalence of the X-ray pattern and optical properties with the synthetic compound, and chemical behavior as a peroxide. Occurrence: A very rare mineral in the oxidized zone of some uranium-bearing mineral deposits. Association: Uranophane, rutherfordine, lepersonnite (Shinkolobwe, Congo); billietite, uranophane, rutherfordine, barite, quartz, hematite, “limonite” (Menzenschwand, Germany); tengchongite, calcurmolite, kivuite (Tengchong Co., China).
