Aberration-corrected electron microscopy of nanoparticles by Yacamán, Miguel José, Santiago, Ulises, Mejía Rosales, Sergio

“…The early history of scanning transmission electron microscopy (STEM) is reviewed as a way to frame the technical issues that make aberration correction an essential upgrade for the study of nanoparticles using STEM. The principles of aberration correction are explained, and the use of aberration-corrected microscopy in the study of nanostructures is exemplified in order to remark the features and challenges in the use of this measuring technique…”

Surface plasmon excitation and manipulation in disordered two-dimensional nanoparticle arrays by Coello, Víctor, Cortes, Rodolfo, García Ortiz, César Eduardo, Elizondo V., Nora

“…We present experimental and numerical results of simultaneous surface plasmon polariton (SPP) excitation and in-plane manipulation with random arrays of gold nanoparticles. The recorded images were obtained by using leakage radiation microscopy (LRM) for the excitation wavelength of 633 nm and for di®erent densities of particles. …”
