The reduction of nitroarenes using KBH and I is described. BI is generated in situ and was shown to be the active reductant. Conditions were optimized for BI generation and then applied to a wide range of nitroarenes, including traditionally challenging substrates.

Experimental data demonstrate that p-channel transistors with SiON layers characterized by a higher nitrogen concentration have poorer NBTI reliability compared to their counterparts with a lower nitrogen content, while PBTI in n-channel devices is negligibly weak in all samples independently of the nitrogen concentration. The Weibull distribution of HBD fields extracted from experimental data in devices with a higher N density are shifted towards lower values with respect to that measured in MOSFETs, and SiON films have a lower nitrogen concentration.

After post-deposition annealing (PDA) and SF6 plasma treatment, the hole mobility is improved. From low-frequency noise analysis, reduction of the trap density and noise level is observed in PDA- and SF6-plasma-treated devices.
