To achieve the respective samples a new fabrication method called double inking is developed, to achieve multiple-height pillar structures.
The height of pillar arrays can be adjusted by controlling the etching duration, which is proved to be of importance in tailoring the antireflection properties of subwavelength structures surface.
As expected, the optical and magneto-optical effects sensitively depends on the geometrical parameters of our structure, which can be simply tailored by the height of pillar, the diameter of mushroom cap, and the period of the structure, and so on.
Also, Fig. 1c, d depict the plan view and the side view of cylindrical pillars, in which r p, h p, and d p are the radii of the pillars, the height of the pillars, and the spacing between the pillars, respectively.
Case studies are given to arrest the adverse effects of extraction height on pillars.
As highlighted in the Fig. 4d, the combined effects of reduction in the VOC and FF, and increase in the ISC with an increase in the pillar height, lead to an optimum height for maximum solar cell efficiency.
A reduction in the VOC and FF and increase in the ISC, with pillar height increase, lead to an optimum pillar height for the highest efficiency gain.
To obtain a stable Cassie drop, the condition that the pillar height must be higher than the sag height of the meniscus is a necessary, yet not a sufficient, condition.
The micro-pillars are designed in I-shape to separate plasma from blood where the diameter and height of each pillar is 12μm and 15μm respectively and the distance between the pillars are 8μm at the middle and 2μm at the edges.
The effect of the pillar height on the acoustic response was tested by measuring the adsorption of BSA; increasing the pillar height up to 155 nm led to an increase in the acoustic phase response associated with wave velocity.
