In this article, we report the defect-gradient-induced helicity-dependent THz emission in PtTe2thin films grown by a modified two-step chemical vapor deposition (CVD) method. The main Te-vacancy (VTe) defect is created during crystal growth along the depth orientation, as evidenced by adaptive-...
The measurement was performed with the large-acceptance detector DAPHNE at the tagged photon beam facility of the MAMI accelerator in Mainz. Both the measured unpolarized and the helicity-dependent observables are not well described by the existing theoretical models. Communicated by Z.-E. Meziani...

Furthermore, helicity-dependent imaging is demonstrated by the terahertz spin Hall metalens. The uniqueness and robust approach for manipulating spin photons may have a significant impact on designing ultra-compact and multifunctional devices and spin photonics devices. Keywords: geometry phase; helicity-...

Helicity filteringWeyl semimetalsKlein tunnelingWeyl fermions are characterized by definite helicity, a relation between orientation of the spin and momentum. We investigate controlling helicity utilizing helicity-dependent dynamics due to separation between the Weyl points. We study transport properties of a...
