Undergrad Understanding Quantum Cascade Lasers
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...- Karl330

Undergrad Understanding Quantum Cascade Lasers
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...- Karl330

Graduate How Does the Darwin Reflectivity Curve Apply to Multi-Layered X-ray Scattering?
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...- Karl330

Undergrad Xray NanoDiffraction of Si and SiGe
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! -What is the difference between a rocking...- Karl330
