Agrowing avenue for determining the prevalence of life beyond Earth is to search for “technosignatures” from extraterrestrial intelligences/agents. Technosignatures require significant energy to be visible across interstellar space and thus inten

Evaluation of Si:HfO2 Ferroelectric Properties in MFM and MFIS Structures

Autor: Jackson D. Anderson, Jordan Merkel, David Macmahon, Santosh K. Kurinec

Publikováno v: IEEE Journal of the Electron Devices Society, Vol 6, Pp 525-534 (2018)

A 10.5 nm silicon doped HfO2 film is deposited and examined on three different bottom electrodes: a TiN electrode such as would be found in capacitive FeRAM, a lightly doped p-Si substrate as would be present in an FeFET, and an n+ Si electrode. The

The key challenge in the observation of the redshifted 21-cm signal from cosmic reionization is its separation from the much brighter foreground emission. Such separation relies on the different spectral properties of the two components, although, in
