Abstract

An interlayer tunneling technique has been used for spectroscopy of charge density wave (CDW) energy gaps (Δ1,2) in NbSe3 subsequently opened at the Fermi surface on decreasing temperature at T p1 = 145 K (CDW1) and at T p2 = 60 K (CDW2). We found that the CDW2 formation is accompanied by an increase of the CDW1 gap below T p2. The maximum enhancement of Δ1, δΔ1 is about 10%. The effect observed has been predicted theoretically as resulting from the joint phase locking of both CDWs with the underlying crystalline lattice below T p2.
