Yui (Matthias) Tan, Woo-Suhl Cho, Muhammad Usman, Gerhard Klimeck |
Objective/Problem:
- Understand experimental Red Shift due to Quantum Confined Stark Effect (QCSE)
- Comparison of Quantum Confined Stark Effect in identical and non-identical QD stacks
Approach:
- Realistic multi-million structures in NEMO-3D
- Dome shaped Quantum Dots
- Identical: D=15nm,15nm; H=3nm
- Non-identical: D=15nm,13nm; H=3nm
- 10nm cap, 25nm substrate, 0.5nm WL
- ary vertical quantum dot distance
- In-plane Electrical Field [-20kV/cm,20kV/cm]
Expected Results:
- Consistency of simulation results with symmetric experimental Quantum Confined Stark Effect
- Feasibility to calculate value of polarizability
