Determination of Crystal Structures

Determination of Crystal Structures

In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...

Background:

Achieving atomically sharp interfaces in quantum well and quantum dot heterostructures remains a significant challenge.
Nanowires offer a unique platform for band structure engineering through controlled crystal phase switching between zinc-blende (ZB) and wurtzite (WZ) phases.
Crystal phase switching in nanowires creates crystal phase quantum wells (CPQWs) and dots (CPQDs).

Purpose of the Study:

To demonstrate the digital tuning of visible emission in WZ/ZB/WZ CPQWs within GaP nanowires.
To investigate the effect of barrier thickness on the optical properties of CPQWs.
To explore the potential of these structures for applications in quantum information processing.

Main Methods:

Fabrication of GaP nanowires with controlled WZ/ZB/WZ heterostructures.
Utilizing crystal phase switching to form quantum wells.
Characterizing the optical emission properties by varying the thickness of the ZB barrier layer.

Main Results:

Demonstrated digital tuning of visible emission by precisely controlling the ZB barrier thickness in GaP CPQWs.
Observed uniform energy spacing between sharp emission lines, directly correlated with the addition of single ZB monolayers.
Identified inherent electric fields at WZ/ZB junctions causing charge carrier confinement and novel transition mechanisms.

Conclusions:

Controlled growth of identical quantum wells with atomically flat interfaces is achievable.
Digitally tunable discrete emission energies can be realized in GaP CPQWs.
This approach offers a promising new route for advancing entangled photon generation in solid-state quantum systems.
