New organic electro-optic crystals based on acentric core OHQ exhibit excellent nonlinear optical properties and crystal characteristics, which show one order of magnitude higher THz generation efficiency than inorganic ZnTe.
In this study, a crawling robot belonging to soft morphing structures using a shape memory alloy (SMA) wires embedded smart soft composite (SSC) was designed and fabricated. In order to obtain a high movement speed, the active components, SMA wires, were placed to go through the whole body to increase robot stride length. Then, the performances of the prototype including deformation measurements,...
The performance of AFM is determined by the control gains. The gains have uncertainties which are impacted by a cantilever, sample properties and environment. In commercial AFM, the controller is manually tuned by user. In this paper, auto gain tuning algorithm is suggested for the high performance and automation of AFM.
A simple but effective way to create a selective emitter is by using laser doping (LD) to selectively remove the anti-reflection coating (ARC) layer and simultaneously melt the silicon underneath it while incorporating dopants into the melted region, creating a heavily doped layer. In conjunction with LD, a plating technique is often used to selectively plate self-aligned metal contacts onto the laser...
