The technique combines two important components: azimuthal rotations around the Bragg wavevector and polarization analysis of the Bragg intensities in the range 500–900 eV. The polarization analysis is performed …
WebIn these models, the CDW wavevector is determined by competition between the CDW’s intrinsic ordering wavevector and coupling between the CDW and another degree of freedom, such as the SDW. The low-temperature wavevector may consequently not reflect the formation mechanism for these phases. WebTo create a shipment wave, simply navigate to Warehouse > Shipment Wave.
