1. 1. Black phosphorous sample preparation for ultrafast electron diffraction studies

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Nyckelord :Graphene; Black phosphorus; electron diffraction; 2D material; Technology and Engineering;

   Sammanfattning : Since 2004 when mechanical exfoliation was first utilised to produce single layered samples of graphite, 2D materials have gained interest in the scientific community. With the prerequisite that the initial bulk material has a layered structure, these 2D materials have created an opportunity to examine materials on a very small scale as well as opening the possibility of creating smaller electrical components for industrial and commercial use, with well-known and documented parameters.

3. 2. Low-Frequency Noise in TFETs

   Master-uppsats, Lunds universitet/Fysiska institutionen

   Författare :Markus Hellenbrand; [2015]
   Nyckelord :Tunnel Field-Effect Transistor; Steep-Slope Devices; III-V; InAs; GaSb; Broken Band Gap; Physics and Astronomy;

   Sammanfattning : Nanowire tunnel field-effect transistors (TFETs) were investigated by carrying out noise measurements and low-temperature DC measurements. The TFET tunnelling junction was realised by a GaSb/InAs heterojunction resulting in a broken band gap. TFET noise currents were measured at frequencies between 10 Hz and 1 kHz. LÄS MER
