Why conventional feedback comes too late<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

The decisive changes happen during growth, not after it<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Critical changes in symmetry, phase, and functionality emerge during deposition and processing. Yet conventional characterization usually starts only after the process is paused, the sample is removed, and valuable time has already been lost. This delays feedback, slows iteration, and leaves key transient behavior unobserved.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
