1. 1. Detection of Contaminants in Water Using Surface Enhanced Raman Spectroscopy

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Freja Hansson; [2021]
   Keywords : Raman; Surface-enhanced Raman Spectroscopy; nanoparticles; contaminants; plasmonics;

   Abstract : Due to deteriorating water quality and the world’s increasing demand for clean water, the need for cheap, easy and portable techniques to characterize and quantify pollutants in waters is urgent. Hence, surface-enhanced Raman spectroscopy (SERS) have gained considerable attention in this field. READ MORE

3. 2. Quantification using SERS on a colloidal substrate

   University essay from Uppsala universitet/Fasta tillståndets fysik

   Author : Kasper Eliasson; [2021]
   Keywords : SERS; spectrometry; nano technology; plasmonics;

   Abstract : This thesis explores the practical usefulness of surface enhanced Raman spectroscopy on a colloidal substrate for quantification of organic analytes in a water matrix. The method evaluated is very simple and accessible as it utilizes a commercially available hand held Raman spectrometer and citrate reduced silver colloid substrate. READ MORE

4. 3. Spectroelectrochemical analysis of the Li-ion battery solid electrolyte interphase using simulated Raman spectra

   University essay from Uppsala universitet/Fasta tillståndets fysik

   Author : Edvin Andersson; [2020]
   Keywords : Lithium Ion Battery; Solid Electrolyte Interphase; Surface Enhanced Raman Spectroscopy; Density Functional Theory; LIB; SEI; SERS; DFT;

   Abstract : Lithium Ion Batteries (LIBs) are important in today's society, powering cars and mobile devices. LIBs consist of a negative anode commonly made of graphite, and a positive cathode commonly made from transition metal oxides. Between these electrodes are separators and organic solvent based electrolyte. READ MORE

5. 4. Properties of III-V/Si heterojunction fabricated by HVPE

   University essay from KTH/Tillämpad fysik

   Author : Prakhar Bhargava; [2020]
   Keywords : ;

   Abstract : Silicon is a promising material and is used for a wide range of applications in the electronics industry because of the high quality surface passivation given by the native oxide layer SiO2e. However, Si is not an ideal candidate for optoelectronic applications due to its indirect bandgap of 1. READ MORE

6. 5. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jonas Segervald; [2019]
   Keywords : AFM; NIL; SPR; SERS; nanohole; nanohole array; nanoimprint lithography; physical vapor deposition; plasma treatment; plasmonic; plasmons; surface plasmon resonance; localized surface plasmon resonance; metal enhanced fluoresence; surface enhanced raman spectroscopy; transmittance; nanoplasmonic; signal enhancement;

   Abstract : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. READ MORE
