The effect of isothermal annealing on the depth profiles of nitrogen atoms implanted into synthetic diamonds is studied by secondary-ion mass spectrometry. The annealing is performed under vacuum at 1400°C for 1, 5, or 20 h. It is found that the dep

The special features of redistribution of phosphorus implanted into silicon wafers with a high concentration of boron (NB=2.5×1020 cm−3) were studied. It is shown that, in silicon initially doped heavily with boron, the broadening of concentration

The temperature range in which oscillating impurity distributions are formed in heavily boron-doped silicon irradiated with boron ions B+ is found. It is hypothesized that the effect is associated with boron clustering processes which proceed more ef
