Anisotropic ultrasensitive PdTe2-based phototransistor for room-temperature long-wavelength detection.

The article discusses emergent topological Dirac semimetals afford fresh pathways for optoelectronics, device implementation has elusive to date. Topics include palladium ditelluride combining the capabilities provided by peculiar band structure, with topologically protected electronic states; and a responsivity of 10 A/W and a noise-equivalent power lower than 2 pW/Hz0.5 are achieved at room temperature.
