Highly Efficient, Charge Depletion-Mediated, Voltage-Tunable Actuation Efficiency And Resonance Frequency Of Piezoelectric Semiconductor Nanoelectromechanical Systems Resonators
View pageUS Patent:
8044556, Oct 25, 2011
Filed:
Jul 30, 2007
Appl. No.:
11/830653
Inventors:
Sotirios Konstantinos Masmanidis - Pasadena CA, US
Rassul Bulatovich Karabalin - North Hills CA, US

Assignee:
California Institute of Technology - Pasadena CA
International Classification:
H01L 41/04
US Classification:
310330
Abstract:
A nanoelectromechanical systems (NEMS) device and method for using the device provide for a movable member that includes a region of low conductivity over which an electric field is developed. A region width is within a factor of ten (10) of a thickness of the NEMS device. The region is formed between a junction that incorporates piezoelectric material. A first voltage is applied across the region which alters a width of an active portion of the region thereby adjusting a movement of the movable member induced by a second voltage. The second voltage is applied across the region to produce a strain on the active portion of the region. The strain results in a defined movement of the movable member.

International Classification:
H03H 9/00
US Classification:
333197
Abstract:
A system, device, method, and apparatus provide the ability to wire a voltage sensitive device to a nanoelectromechanical system (NEMS) resonator. A voltage sensitive device is configured to detect one or more voltage signals and output one or more electrical potentials in real-time. An array of piezoelectric NEMS resonators (with each resonator tuned to a unique frequency) is used to receive the output electrical potentials and convert each output electrical potential to a corresponding resonance frequency varying signal. The output signal from each resonator varies in linear proportion to the resonator's corresponding frequency variation arising from the applied elecrical potential. The frequency varying signals are multiplexed together into a single readout signal path that is monitored to determine variations in vibrational amplitude. A demodulation device deconvolves the multiplexed frequency varying signals to recover and uniquely identify the output electrical signal.

G02F 1/37
US Classification:
436 94, 359328
Abstract:
Second harmonic nanoprobes for multipurpose imaging of samples and a method of using such probes to monitor nucleotide sequencing in a Multi-SHG Detection Imaging (MSDI) modality and to monitor external electric field using voltage sensitive second harmonic generating (SHG) nanoprobes are provided. The SHG nanoprobes are comprised of various kinds of nanocrystals that do not possess an inversion symmetry and therefore are capable of generating second harmonic signals that can then be detected by conventional two-photon microscopy for in vivo imaging of biological processes and structures such as cell signaling, neuroimaging, protein conformation probing, DNA conformation probing, gene transcription, virus infection and replication in cells, protein dynamics, tumor imaging and cancer therapy evaluation and diagnosis as well as quantification in optical imaging for a wide-range of biological and non-biological processes and devices.
