摘要：

On bulk single phase V3Si single crystals (residual resistivity ratio ϱ(293 K)/ϱ(17.5 K) = 15 to 30) tunnel junctions are prepared by different preparation methods. The tunnel characteristics obtained by means of modulation technique yield energy gap values in the range of δo = (1.93 to 2.66) meV on a lot of different tunnel junctions. The relation 2δo/kTc > 3.52 found on some junctions indicates strong electron‐phonon interaction. Above the energy gap phonon induced structures are found in some tunneling characteristics.
