1. 1. Towards Long-Range Backscatter Communication with Tunnel Diode Reflection Amplifiers

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Gustav Eriksson; [2018]
   Keywords : Amplified backscatter tag; Reflection amplifier; Battery-free; Long-range communication; Tunnel diode; Ultra-low power consumption; RFID; Frequency shift;

   Abstract : Backscatter communication enables wireless communication at a power consumption orders of magnitude lower than conventional wireless communication. Instead of generating new RF-signals backscatter communication leverages ambient signals, such as WiFi-, Bluetooth- or TV-signals, and reflects them by changing the impedance of the antenna.

3. 2. Simulation and analysis of InP/GaInP nanowire Esaki diodes for photovoltaic device applications

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

   Author : Odd Restad; [2017]
   Keywords : Physics and Astronomy; Technology and Engineering;

   Abstract : In this thesis the WKB-approximation is used to simulate the tunneling current for an Esaki nanowire diode and the result is compared to data from Esaki nanowire diodes grown with MOVPE. The WKB-approximation with triangular potential barrier predicts a strong increase of the tunneling current as a function of the doping densities and at the highest doping levels it gives lower tunneling distances than more reliable drift-diffusion simulations and is thus overestimating the current.
