1. 1. Nanolithography with molecules using advanced scanning probe microscopy methods

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Johan Jirlén; [2018]
   Nyckelord :cSPL; AFM; nanolithography; enzyme; starch; amylase; immobilization;

   Sammanfattning : The possibilities of novel catalytic scanning probe lithography (cSPL) on starch using α-amylase was investigated. For this thin homogeneous layers of starch with good coverage were prepared by spin coating a starch solution on a silicon base. LÄS MER

3. 2. Carbon Nanotube Raman Spectra Calculations using Density Functional Theory

   L3-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Johan Jirlén; Emil Kauppi; [2017]
   Nyckelord :Density Functional Theory; DFT; Single-Walled Carbon Nanotubes; SWCNTs; Raman; Spectra; VASP;

   Sammanfattning : Utilizing density functional theory (DFT) the Vienna Ab initio Simulation Package (VASP) was used to calculate the Raman spectra for five single-walled carbon nanotubes (SWCNTs) with chiralities (4,4), (6,6), (8,0), (12,0) and (7,1). The radial breathing mode (RBM), when compared with experimental frequencies, shows good correlation. LÄS MER
