摘要： A laser ablation process is applied to a semiconductor substrate causing the semiconductor material surface and subsurface to be superheated to the point where material is ablated from the material substrate. Optional subsequent laser pulse(s) liquefy the particles, preferably while suspended in air, and the material surface tension causes the liquefied droplet of semiconductor material to form a sphere. The droplet preferably solidifies in air before reaching the substrate of its origin or another substrate for collection.

摘要： A microbot includes a spherical housing, first and second servomotors that are located internal to the housing and oriented horizontally and orthogonal to each other, and a plunger within the housing that selectively extends in the vertical direction. Castors are attached to each servomotor; and traction balls corresponding to each castor are placed so that each ball frictionally engages both a respective castor and the interior of the housing at the same time. As the servomotors rotate, the attached castors also rotate, which causes rotation of the traction balls and rolling of the housing, and results in translation of the microbot in the horizontal plane. As the plunger rapidly extends, it strikes the interior surface of the housing with sufficient force to cause a hopping motion of the microbot in the vertical direction.

摘要： A scanning probe microscopy head may include a base portion, cantilevers coupled to the base portion, and at least one tip coupled to each of the cantilevers. At least two of the cantilevers and associated tips may be configured to perform a different scanning probe microscopy technique. The cantilevers may be positioned perpendicular to the base portion and may be coupled to the perimeter of the base portion. The base portion may include circuitry coupled thereto for providing electricity to the tips. The cantilevers may each be placed into a recessed slot along the perimeter of the base and secured to the base by a securing mechanism, such as a spring clip. The cantilevers may be operatively coupled to a linear positioner, such as a piezoelectric motor, coupled to the perimeter of the base for controlling the amount of protrusion of the cantilevers from the perimeter of the base.

摘要： Methods enable the capture and manipulation of minute particles. One method includes locating a particle on a specimen stage; generating a finite-length open-ended hollow tube laser output around the particle; generating opposing end-cap laser outputs at either end of the hollow tube laser output to enclose the particle; and moving at least one of the specimen stage, hollow tube laser output and end cap laser outputs to re-position the particle. Another method includes locating a particle on a specimen stage; generating a first finite-length open-ended hollow tube laser output around the particle; generating a second finite-length open-ended hollow tube laser output around the particle, whereby the particle becomes enclosed at the intersection of the first and second hollow tube laser outputs; and pivoting at least one of the first and second hollow tube laser outputs such that the particle is re-positioned.

摘要： A system includes at least two optical fibers crossing to form a vertice. The optical fibers comprise a core, a cladding surrounding the core, and a conductive coating at least partially surrounding the length of the cladding. A portion of the core of each of the fibers is exposed proximate to the vertice. An optical microsphere whispering gallery mode (WGM) resonator is positioned to cover exposed core portion of each fiber and in contact with the conductive coating of each fiber. The optical fibers may be orthogonal to each other or offset by a non-orthogonal and non-zero angle. The WGM resonator may be positioned between each of the fibers. An optical energy source may be coupled to an end of the optical fibers, with an optical detector coupled to the other end. A voltage source may be connected to the conductive coating of each of the optical fibers.
