“…Necking is a well-known sintering mechanism, primarily driven by surface diffusion and influenced by variables such as contact surface, temperature, and time. In the case of the electric field-assisted sintering technique (FAST), bonding occurs at the atomic level, involving atomic defects, grain boundaries, and electromigration, in addition to necking [26]. The mechanisms of FAST are largely influenced by process variables, including circuit current, voltage, and conductivity [20].…”

“…When annealing temperatures further increase over 700 °C (Figure 1s; Figure S2f,g, Supporting Information), no noticeable GBs are observed on each island, which indicates that the high temperature causes melting of the NPs, inducing complete coalescence and consolidation of the NPs to form a single grain. [47,53] The rounded border of each island also indicates that NP melting proceeds during annealing at those temperatures. Consequently, it is confirmed that a uniform CoO x thin film with GB networks cannot be obtained by the conventional thermal annealing process.…”

“…In addition, the in situ straining at room temperature can be augmented by additional heating or cooling capabilities, enabling researchers to investigate the nanomechanical behavior of materials at high or low temperatures (Fang et al, 2021;Wang et al, 2021). Cooling is achieved by connecting a cold finger to a liquid helium or nitrogen reservoir at the end of the sample holder.…”
