1. 1. Design and Modeling of InxGa(1−x)As/InP based Nanosheet Field Effect Transistors for High Frequency Applications

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Hanyu Liu; Xi Chen; [2023]
   Nyckelord :nanosheet NS ; gate-all-around GAA ; channel release; parasitic channel; MATLAB; COMSOL; technology node; Technology and Engineering;

   Sammanfattning : The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. LÄS MER

3. 2. A Simulation Study of Variability in Gate-all-Around Nanosheet Transistors

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Virinchi Tirumaladass; [2022]
   Nyckelord :Gate-all-around; Nanosheet field effect transistors; process variations; variability; TCAD; Gate-all-around; Nanoblad fälteffekttransistorer; processvariationer; variabilitet; TCAD;

   Sammanfattning : Gate-all-around (GAA) nanosheet field effect transistors (NSFETs) seem to be one of the most promising replacement options for FinFETs towards scaling down below to the sub-7nm technology nodes. They offer better electrostatics and control of short channel effects (SCEs) due to their superior control over the channel and their large effective channel width. LÄS MER

4. 3. Development of covalent organic frameworks for energy storage applications : DAAQ-TFP COF and MXene composite electrodes for proton cycling

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

   Författare :Simanjit Singh; [2022]
   Nyckelord :covalent organic framework; DAAQ-TFP; MXene; composite electrodes; 1 3 5-Triformylphloroglucinol; 2 6-Diaminoanthraquinone; nanosheets; exfoliation; ex-situ; Ti3C2Tx;

   Sammanfattning : The demand for today's material resources for energy storage is rapidly increasing and can result in both environmental and political conflicts that can affect the development of electronic devices due to high prices and limitations of raw materials for batteries. In this study, potential future composite electrodes were synthesised with an ex-situ approach by compositing redox-active 2,6-Diaminoanthraquinone and 1,3,5-Triformylphloroglucinol covalent organic framework (DAAQ-TFP COF) with conductive delaminated Ti3C2Tx MXene to maximise the number of redox-active moieties during cycling.

5. 4. Investigation of graphene and nanocellulose hybrid films as a barrier material in packages

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Jens Bodelsson; [2019]
   Nyckelord :Nanocellulose; CNF; Graphene; Barrier; Dispersion; graphene nanosheets; coating; sonication; carboxymethylated; polymer technology; polymerteknologi; Technology and Engineering;

   Sammanfattning : In this report, hybrid films of carboxymethylated cellulose nanofibrils (CNF) and graphene nanosheets (GNs) have been prepared to evaluate if the GNs can enhance the barrier properties of the CNF films. CNF already possess great barrier properties at low relative humidity (RH) but it is drastically lowered when the RH reaches above 50% due to its strong hydrophilicity of CNF. LÄS MER

7. 5. MICROWAVE ASSISTED SYNTHESIS OF TITANIUM DIOXIDE ELECTRODES FOR USE IN POLYMER DSSC

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Niklas D.J. Hansen; [2014]
   Nyckelord :;

   Sammanfattning : It’s widely known that microwaves can be a useful tool when it comes to heating many different kinds of materials. It’s much less known however that compared to regular convective heating it can exhibit catalytic properties. LÄS MER
