Today I got to visit the new microscopy labs on the floor below my office. This is the star of the show: a 3 meter tall scanning tunneling electron microscope with 0.6 angstrom resolution. Wow. At a training event today on delivery of educational school workshop on semiconductors 'Generation Tech', which we have been working on with #sciencemadesimple. Looking forward to seeing this roll out to local schools very soon. Here is one of the exercises about pixellation and imaging: can you recognise these #bennettlabcardiff researchers? New lab! These photos were taken over 5 days as we moved 1 mile north to the new facility. Thanks to all the group for their hard work. Moving one of the big optical tables on the hottest ever day in the UK. If only the lift had been a few centimetres bigger... Crates arrived in the lab for packing all our equipment, ready to move to the new Translational Research Hub. I have known this moment was coming for almost 5 years, so am prepared. Will post lots of updates in the next few weeks as we settle into our new home. One way to quantum technology. My group has published paper today on quantum light emission from colour centres in Gallium Nitride at https://doi.org/10.1063/5.0085257. This semiconductor is used in numerous everyday applications including room lighting, car headlamps, high power electronics and blu-ray (if you are old enough to remember what that is?). We showed the use of a half-sphere lens on the semiconductor can greatly enhance the magnification with which we image these colour centres, and also increases the intensity of the emission. Well done to all the team on getting this paper out. The scanning electron microscope in the Cardiff Cleanroom. A visit to our new labs!
