Quantum emitters in hexagonal boron nitride (hBN) have attracted significant interest due to their bright and narrowband photon emission even at room temperature. The wide-bandgap two-dimensional material incorporates crystal defects of yet-unknown c

Abstract Background Education can create better opportunities for health, and vice versa. Using a so-called ‘add-in’ approach, school-based physical activity (PA) promotion and prevention of sedentary behaviours can increase pupils’ wellbeing a

Symposium Latsis 2019 on Diamond Photonics - Physics, Technologies and Applications.
We show that changing the spontaneous emission rate of nitrogen-vacancy (NV) centers in diamond through Purcell enhancement can modify the optical readout signal-to-noise ratio for electron spins. We study the effect experimentally with single NV cen

En femtedel af danske grundskoler praktiserer udeskole, der er regelmæssig undervisning udenfor skolens mure i folkeskolens almindelige fag. Centrale indsatser for udbredelse af udeskole, åben skole og bevægelse i undervisningen har bidraget til u

Research has shown that physical activity (PA) is important for health throughout the lifespan. Therefore, it is important that children develop the individual prerequisites that enable participation in PA throughout life. The theoretical concept phy

We demonstrate that the quasi-one-dimensional (1D) current transport, experimentally observed in graphene as measured by a collinear four-point probe in two electrode configurations A and B, can be interpreted using the sensitivity functions of the t

It is generally accepted that nitrogen-vacancy (NV) defects in bulk diamond are bright sources of luminescence. However, the exact value of their internal quantum efficiency (IQE) has not been measured so far. Here we use an implementation of Drexhag

Commercial elastomer materials are available for dielectric electroactive polymer (DEAP) purposes but the applied commercial elastomers have not been developed with the specific application in mind. It is therefore obvious that optimization of the el

The presence of defects in graphene have for a long time been recognized as a bottleneck for its utilization in electronic and mechanical devices. We recently showed that micro four-point probes may be used to evaluate if a graphene film is truly 2D
