Emergence of charge density waves and a pseudogap in single-layer TiTe2

Emergence of charge density waves and a pseudogap in single-layer TiTe2

Two-dimensional materials constitute a promising platform for developing nanoscale devices and systems. Their physical properties can be very different from those of the corresponding three-dimensional materials because of extreme quantum confinement and dimensional reduction. Here we report a study of TiTe2 from the single-layer to the bulk limit. Using angle-resolved …
