| Description | Demonstrated extreme control of epitaxy process to produce stacks of 500 layers, each precisely defined with thickness in the few nm range and a tolerance of 0.2 nm achieved. |
| Exploitation Route | The epitaxy control could be utilised in future multi-layer devices with applications in photonics, electronics or thermoelectrics. The progress made on n-type Ge QCL structures can be further developed and could yet produce a Si-based laser. |

| Results and Impact | A public engagement lecture presented by Dr John Halpin (who was funded on EPSRC research grant as first a PhD student and then a postdoc) as part of the University of Warwick Materials Week. The lecture drew on his EPSRC funded research to explain concepts of materials, semiconductors and lasers to an audience of 250 upper primary/lower secondary school children, their parents, and local Scout/Guide groups. |
