1. 1. Analysis of condition for ALD deposition of ferroelectric HZO

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Teodor Qvint; [2022]
   Keywords : HZO; Ferro; ALD; Temperature; Purge time; Technology and Engineering;

   Abstract : Deposition of ferroelectric hafnium zirconium oxide (HZO) on semiconductor samples with Atomic Layer Deposition (ALD) has proven to be a viable method of production. But while the physical processes of ALD deposition is relatively well know, there exists some gaps in knowledge about different parameters for the ALD and the resulting depositions. READ MORE

3. 2. Design and Verification of An Energy-Efficient Edge-Pursuit Comparator

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Haiqin Xie; [2022]
   Keywords : analog to digital converter ADC ; SAR; comparator; edge-pursuit comparator EPC ; edge-pursuit comparator enhanced with capacitor EPCC ; energyefficient.; analog till digital omvandlare ADC ; SAR; komparator; edge-pursuit komparator EPC ; edge-pursuit komparator förbättrad med kondensator EPCC ; energieffektiv.;

   Abstract : With the rapid development of mobile communication, sensors, and biomedical in recent years, the demand for accurate data information, highquality audio and image has become much more significant, which requires a high-precision Analog to Digital Converter (ADC) to process weak analog signals. As one of the core modules of ADC, the comparator’s precision, speed, stability, and noise play a key role in the performance of the whole circuit. READ MORE

4. 3. Study of solution-based Cs0.1FA0.9Pb(I0.9Br0.1)3 perovskite deposition with scalable technology for solar cell production : Characterization of optical properties and function of the solar cell

   University essay from Uppsala universitet/Fysikalisk kemi

   Author : Tasnim Laskar; [2021]
   Keywords : ;

   Abstract : Climate change is one of the greatest challenges of the 21st century and is the reason for several environmental changes on earth. One reason behind climate change includes the rise ingreenhouse gas emissions in the atmosphere due to the burning of coal, gas and oil, i.e. fossil fuels. READ MORE

5. 4. Ferroelectricity in nanocrystalline Hf0.5Zr0.5O2 thin films

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Lun Sang; [2018]
   Keywords : ferroelectricity; Hf0.5Zr0.5O2; GIXRD; XRR; Technology and Engineering; Physics and Astronomy;

   Abstract : Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. READ MORE

6. 5. Power-Efficient Settling Time Reduction Techniques for a Folded-Cascode Amplifier in 1.8 V, 0.18 um CMOS

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Author : Jimmy Johansson; [2017]
   Keywords : Folded-Cascode; Settling Time; Settling Time Reduction; Slew Rate; Slew Rate Enhancement; Operational Amplifier; Recycling Folded-Cascode; 180 nm CMOS; Test Buffer; Power-Efficient; Single-Stage Amplifier; Linear Settling Period; Slewing Period;

   Abstract : Testability is crucial in today’s complex industrial system on chips (SoCs), where sensitive on-chip analog voltages need to be measured. In such cases, an operational amplifier (opamp) is required to sufficiently buffer the signals before they can drive the chip pad and probe parasitics. READ MORE
