摘要
Experiment and simulation are combined to demonstrate that, provided that thermal effects are limited, the dielectric breakdown of SiO2 films in MOS devices opens atomic-size conduction channels (with radius in the 1 to 18 nm range) which behave as point contacts. Depending on the size of the breakdown spot, the conduction properties are either those of a Sharvin point contact or those of a quantum point contact.
