1. 1. Characterizing optical and electrical properties of monolayer MoS2 by backside absorbing layer microscopy

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Nathan Ullberg; [2020]
   Keywords : backside absorbing layer microscopy; BALM; monolayer MoS2; TMD; TMDC; 2D materials; nanomaterials; nanotechnology; refractive index; extinction coefficient; absorption coefficient; field-effect transistor; FET; semiconductors; optoelectronics; optics; raw image processing; chemical vapor deposition; CVD; in situ characterization;

   Abstract : Nanomaterials are playing an increasing role in novel technologies, and it is important to develop optical methods to characterize them in situ.  To that end, backside absorbing layer microscopy (BALM) has emerged as a powerful tool, being capable to resolve sub-nanometer height profiles, with video-rate acquisition speeds and a suitable geometry to couple live experiments.

3. 2. Sputtering of High Quality Layered MoS2 films

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Sari Abid Al Shaybany; [2020]
   Keywords : MoS2; molybdenum; molybdenum disulfide; sputtering; magnetron sputtering; high quality; sulfur; H2S; argon; pressure; temperature; high temperature; monolayer; few layers; large scale;

   Abstract : We have deposited bulk, monolayer and few-layers as well as large-scale 2D layered MoS2 thin films by pulsed DC magnetron sputtering from an MoS2 target. MoS2 has gained great attention lately, together with other layered Transition Metal Dichalcogenides (TMDCs), for its unique optical and electrical properties with thickness-dependent bandgap.
