摘要：
We have studied the influence of laser radiation on the structure and electrophysical properties of resistive thick films based on BaB6-LaB6 solid solution. It has been shown that, in the course of laser treatment in the millisecond range, barium and lanthanum diffuse into the substrate, and micro-and nanosecond laser radiation leads to the breakup of current-conducting chains and the formation of domains with discrete structure. We have carried out a differential analysis of voltampere characteristics and determined the temperature dependences of electrical resistance R and resistance temperature coefficient. Laser treatment in the micro-and nanosecond ranges slightly increases the electrical resistance, which can be used for the precision treatment of thick films.
