Abstract: A sensing device that produces a Raman signal includes micro-rods or nano-rods arranged on a substrate in a two-dimensional (2D) array, each of the rods having a length in a single row being substantially the same, with the rod length of each row being different from the rod length of each other row. Each row of rods has a respective resonant vibration frequency that varies from row to row. A source of vibration energy, operatively connected to the substrate, excites vibration in each of the rods such that a responding row resonates when an exciting frequency approaches the resonant vibration frequency of the responding row. A method includes exposing the 2D array to a light source and analyzing Raman scattering at each rod of the 2D array to render a Raman map.

Abstract: A cleave plane is defined in a semiconductor donor body by implanting ions into the wafer. A lamina is cleaved from the donor body, and a photovoltaic cell is formed which comprises the lamina. The implant may cause some damage to the crystal structure of the lamina. This damage can be repaired by annealing the lamina using microwave energy. If the lamina is bonded to a receiver element, the receiver element may be either transparent to microwaves, or may reflect microwaves, while the semiconductor material absorbs the microwaves. In this way the lamina can be annealed at high temperature while the receiver element remains cooler.

Abstract: A vibrating tip surface enhanced Raman spectroscopy (SERS) apparatus, system and method employ a nano-needle configured to vibrate. The apparatus includes the nano-needle with a substantially sharp tip at a free end opposite an end attached to a substrate. The tip is configured to adsorb an analyte. The apparatus further includes a vibration source configured to provide an alternating current (AC) electric field that induces a vibration of the free end and the tip of the nano-needle. Vibration of the nano-needle under the influence of the AC electric field facilitates detection of a Raman scattering signal from the analyte adsorbed on the nano-needle tip. The system further includes a synchronous detector configured to be gated cooperatively with the vibration of the nano-needle. The method includes inducing the vibration, illuminating the vibrating tip to produce a Raman signal, and detecting the Raman signal using the detector.
