We investigated the recently discovered extremely long-period stripe structure (ELPSS) in LaTe3using scanning tunneling microscopy (STM)/scanning tunneling spectroscopy. We found that the contrast of the ELPSS was inverted between STM images acquired at positive and negative setup bias voltages, and that the tunneling spectrum exhibited a spatial variation corresponding to the ELPSS. These results indicate that the ELPSS is a charge density wave (CDW) with an energy gap opening near the Fermi energy and suggest that the bilayer splitting induces the formation of this extremely long-period CDW.

Magnetic Field due to Moving Charges
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
