I understand that a voltage is applied which sends electrons tunneling through barriers and quantum wells but I am confused on what you mean by high and low bandgap materials. For example a 20 period In0.33Ga0.67As (3.1 nm)/Al0.90In0.10As (7.2 nm) is a superlattice that I am studying and I am...
Hello I am struggling to understand the concept of Quantum cascade lasers. I am doing research on a 20 period In0.33Ga0.67As (3.1 nm)/Al0.90In0.10As (7.2 nm) superlattice and would like to fully understand how a quantum cascade laser works. I also have not taken quantum mechanics yet so I...
Hello
What does it mean when people say high resolution xray diffraction? What is the difference between regular Xray diffraction and high resolution X-ray diffraction?
Thank you
Hello I am confused what Coherent X-ray Diffraction Imaging is with real and reciprocal space. Would someone be able to explain this to me like I am 5 years old because I am really not getting it.
Hello I am doing research on kinematic and dynamic scattering of xrays on a crystals. I am attempting to simulate the diffraction patterns of a silicon substrate and I have already simulated two other layers of a Silicon Quantum Well and SiGe from which the hetero structure was composed of. In...
Hello
I have been struggling with my research on xray diffraction of crystals and had a few questions about crystallography, rocking curves(omega scan), θ-2θ scans and diffraction patterns. Let me know if you need more explanation. Thank you!
