Delayed Formation of Landau Polaritons in Phase-Resolved THz Spectroscopy
Noureddine Charrouj, Yurii Ivonyak, Dmitriy Yavorskiy +4
Strong light-matter coupling gives rise to polaritons through coherent and periodic energy exchange between electromagnetic cavity fields and material excitations. While this inter…

Positive Terahertz Photoconductivity in CdHgTe Under Hydrostatic Pressure
Ivan Yahniuk, Dmitriy A. Kozlov, Mariya D. Moldavskaya +10
Positive terahertz photoconductivity is observed at room temperature in CdHgTe thin films with different Cd contents. We show that electron gas heating caused by Drude-like absorpt…

Pressure tuning of HgCdTe epitaxial layers -- the role of the highly disordered buffer layer
D. Yavorskiy, Y. Ivonyak, D. But +9
HgCdTe alloys are unique because by increasing the Cd content x, one modifies the band structure from inverted to normal, which fundamentally modifies the dispersion of bulk and su…
