Recently, there has been great interest in the application of the surface texturing method to enhance material surface performance. Material surfaces sometimes experience rapid temperature changes, and the local surface will obviously generate thermal stresses, which may be detrimental to the material structure. In order to understand the relationship between surface texturing and stresses, a n...

We propose and demonstrate the use of short pulsed fiber lasers in surface texturing using MHz-repetition-rate, microjoule- and sub-microjoule-energy pulses. Texturing of titanium-based (Ti6Al4V) dental implant surfaces is achieved using femtosecond, picosecond and (for comparison) nanosecond pulses with the aim of controlling attachment of human cells onto the surface. Femtosecond and picoseco...

Surface textures have various applications, such as friction/wear reduction and light absorbing enhancement. Deformation-based surface texturing has the potential of economically creating micro-scale surface textures over a large surface area. A novel desktop surface texturing system is proposed for efficiently and economically fabricating microchannels on the surface of thin sheet material for...

Surface texturing has been widely adopted to enhance the light extraction efficiency of light-emitting diodes (LEDs), and chemical etching is a technique commonly used to produce surface texturing. This study employed femtosecond lasers to apply ITO films directly onto the surface of LEDs to generate periodic micro/nanostructures and roughen the surface without contact or chemical substances. A...

design and optimization of a single crystalline silicon (c-si) solar cell is performed to achieve the maximum light conversion efficiency. various parameters such as doping concentration and thicknesses, and geometrical dimension of surface pyramids are studied. the inverted surface pyramid is used to increase the efficiency of the solar cell, and engineered oxide layer is used as the passivati...

This paper presents an interactive environment for texturing surfaces of arbitrary 3D objects. By uniquely using solid textures and applying them to the surface, we do not require an explicit parameterisation in texture space. Various solid textures can be combined by building a constructive texturing tree of space partitions to define the photometric attributes at each location of the object. ...

We present a method for simulation and visualization of a liquid splash motion. The proposed system is composed of a computational fluid dynamics and a polygon based renderer using multi texturing graphical acceleration. The system well supports the NavierStokes solver with adaptive time step and viscosity. The final liquid surface is obtained from the velocity field by rough estimation of the ...

The transmission properties of semiconductor surfaces can be changed by surface texturing. We investigate these changes experimentally and find that an enhancement of the angle-averaged transmission by a factor of 2 can be achieved with optimum texturing parameters. This enhanced transmission provides an additional light extraction mechanism for high-efficiency surface-textured light-emitting d...
