Note: Many potential applications of nanoscale variations with thermal probes such as Scanning Nano Lithography are still applicable in nanoelectronics, especially when extremely high heating and cooling rates can be used.
Many microsystems and nanosystems require precise nanoscale patterns that exhibit intrinsic performance, such as some electronic, photonic, chemical, and mechanical properties. To make these nanoscale patterns, electron beam lithography is the most common lithographic technique without direct writing and without mask. Scanning Nano Lithography requires complex electron-compatible light to focus the electron beam at a point a few nanometers away. Another issue is electron scattering, a kind of proximity effect on the sample surface, which leads to exposure to additional undesirable resistances that must be corrected by intensive computational algorithms.Scanning Nano Lithography is another method of direct nano-lithography writing, in which patterns are created by scanning a nanometer-sharp spot on a sample for local variation. Sample and sample interactions are numerous and can include mechanical, electrical, diffusion, and thermal effects.
In the immersion method, nanowires have enough time to transfer from nanoparticle particles to cavities ; The formation step of uniform nanoparticles is done slowly and finally uniform nanowires are formed. Structural study with FESEM in the immersion method of single-stranded nanowires in all disturbances and in a wide area in nanoparticle particles. Changing the Sr / Fe ratio does not change the morphology of the nanowires. And spectroscopy of nanowires with a ratio of Sr / Fe states within the nano-particles inside (nanowires uniform) elements Fe and Sr of ferrite strontium in spectroscopy nanowires uniform is seen in the sample of nanoparticles Sr / Fe to value Its stoichiometry is closer to the electromagnetic composition of nanoparticles, while Due to the lower solubility of uniform strontium nanowire nanomolecules compared to iron nitrate and the consequent presence of less strontium ions in the reaction with the nanowire electromagnetic particles, there is a greater amount of Fe ion in the final structure. Electromagnetically active particles are used to separate uniform nanowires at ambient temperature . In the application of nanowires in nanoscale electronics or some other applications, it is necessary to separate the nanowires from alumina particles .
Conclusion :
Many potential applications of nanoscale variations with thermal probes such as Scanning Nano Lithography are still applicable in nanoelectronics, especially when extremely high heating and cooling rates can be used.
