Live TEM imaging of Nanowire growth and device dynamics
- Project type: Ph.D project
- Project responsible: Christopher Røhl Andersen
- Supervisors: Kristian Mølhave, Nika Akopian, Kimberly Dick Thelander
- Partners involved: DTU Photonics, NanoLund - Lund University
Project description
I fabricate microdevices at the Technical University of Denmark to study III-V nanowire growth and their electrical and optical properties using the ETEM at nCHREM, Lund University.
The microdevices are based on a microheater design ([1]) and they are fabricated using silicon-on-insulator wafers. The device layer is made by using the maskless aligner at the DTU Nanolab cleanroom followed by a Bosch etching process. Windows are made from the handle using KOH etch and a thin nitride protection layer
