Fermi surface tomography

Publication Type: Academic Journal

Source(s): Nature Communications, Vol 13, Iss 1, Pp 1-6 (2022)

Abstract: The Fermi surface is related to the energy distribution of electrons in a solid, and governs physical properties of metals and semiconductors. A new type of angle-resolved photoemission spectroscopy, probing the Fermi surface and combining short record...

Impact of Climate Change on the Ground Thermal Regime in the Lower Lena Region, Arctic Central Siberia

Publication Type: Academic Journal

Source(s): Land, Vol 12, Iss 19, p 19 (2022)

Abstract: This paper presents the results of 30 years of permafrost thermal monitoring in the Tiksi area in the eastern Russian Arctic. At a stone ridge site, the mean annual temperatures in the upper 30 m of the ground have increased by 1–2.4 °C compared to the...

Mercury in Sediment Core Samples From Deep Siberian Ice-Rich Permafrost

Publication Type: Academic Journal

Source(s): Frontiers in Earth Science, Vol 9 (2021)

Abstract: We determine Hg concentrations of various deposits in Siberia’s deep permafrost and link sediment properties and Hg enrichment to establish a first Hg inventory of late Pleistocene permafrost down to a depth of 36 m below surface. As Arctic warming is ...

Surface displacement revealed by L-band InSAR analysis in the Mayya area, Central Yakutia, underlain by continuous permafrost

Publication Type: Academic Journal

Source(s): Earth, Planets and Space, Vol 72, Iss 1, Pp 1-16 (2020)

Abstract: Abstract Recent increases in global temperature have stimulated permafrost degradation associated with landform deformation caused by the melting of excess ground ice (thermokarst). Central Yakutia is underlain by ice-rich continuous permafrost, and th...
