"This book covers the fundamental developments of plasmonic nanosenor design over the last few years. Jan Becker addresses the relevant theoretical concepts and then applies these to discuss the properties and trends in nanoparticles of various shapes and sizes. The first discovery Jan makes in his PhD research is that there is an optimal shape for plasmonic nanoparticles used for sensing purposes. In further chapters he goes on to describe novel experimental methods to use plasmonic nanoparticles for molecular sensing. Many of the experiments described in this thesis."

"ABSTRAKStudi eksperimen terkini pada sistem oksida stronsium niobat telah mengungkap kemunculan plasmon inkonvensional yang diakibatkan kungkungan bidang-bidang oksigen. Sebuah model fenomenologis yang menyertai data eksperimen pada studi tersebut telah mengindikasikan bahwa elektron yang terkungkung berperilaku sebagaimana osilator harmonik. Hal-hal tersebut memotivasi kami untuk mempelajari lebih lanjut efek kungkungan spasial terhadap elektron dalam pembentukan plasmon inkonvensional pada sistem terbatas. Dinamika elektron terkorelasi pada sistem ini dijelaskan menggunakan model Hubbard 3D untuk ukuran terbatas yang diselesaikan melalui pendekatan medan rata-rata. Kami mempelajari sistem kubus hipotetis yang terdiri dari n × n × n atom berorbital tunggal dengan n adalah 3, 5, 7, dan 9. Kalkulasi dilakukan dengan dan tanpa memperhitungkan repulsi Coulomb on-site Kami juga mempertimbangkan sistem diperpanjang sebagai pembanding untuk mengetahui efek kungkungan. Perhitungan kami menunjukkan bahwa plasmon inkonvensional terbentuk hanya jika kita memperhitungkan efek kungkungan dan repulsi Coulomb on-site.

ABSTRACTRecent experimental study on strontium niobate oxide system has revealed unconventional plasmons generation due to confinement by oxygen planes. A phenomenological model accompanied the experimental data on that study has suggested that the confined electrons behave as harmonic oscillators. These motivate us to further study the effect of space confinement to the electrons on the generation of the unconventional plasmons in a finite-size system. The dynamics of the correlated electrons in this confined system is described using the finite-size 3D Hubbard model that is solved within mean-field approximation. We study a hypothetical cubic systems that consist of n × n × n single-orbital atoms with n being 3, 5, 7, and 9. The calculation is done with and without incorporating the on-site Coulomb repulsion. We also consider extended system as a comparison to know the effect of confinement. Our calculations show that unconventional plasmons are observed only if we take into account both the confinement effect and the on-site Coulomb repulsion."

"Aimed to be a snapshot of progress in the development of a variety of sensors, used in different application fields, this postgraduate-level book combines the work of leading academic authors. The authors of each chapter describe the principles of operation, characteristics and applications of the sensor-type under consideration, but in addition feature recent advances and prospects for future development. These are areas where advances are ongoing so that there is considerable scope for future development activity. Such sensors are applied in many and varied fields of science, measurement and technology."

"This book covers the recent development of the interdisciplinary use of sensors for data collection, systems analysis and monitoring. It presents the latest in theory and practice across a variety of fields such as engineering, biomedicine, and the military."
