The Vicinal Si(100) faces have a reconstruction with double or single steps, depending on the miscut of the surface. In our He-atom-scattering experiment, the reconstruction of the Si(1 1 17) face is investigated versus temperature. The miscut (4.76°) is chosen in such a manner that it is above the threshold where the double steps are always formed. A strong structural modification is observed at high temperatures (above 800 K), and is interpreted as the appearance of the single-step reconstruction. Recent theoretical models predicting the transition are considered and a calculation is done on this basis using recently published experimental values of the energy of kinks on steps.
