A data storage medium is provided according to the present invention for magnetic recording. The data storage medium includes a substrate having a locking pattern etched therein defining patterned regions. The patterned regions are chemically modified by depositing a self-assembled monolayer therein. A first layer of nanoparticles is provided in the patterned regions on top of the self-assembled monolayer and is chemically bonded to the substrate via the self-assembled monolayer. The first layer of nanoparticles is chemically modified using functional surfactant molecules applied thereto, such that a second layer of nanoparticles may be formed on top of the first layer and chemically bonded thereto via the functional surfactant molecules. Additional layers of nanoparticles may be applied by chemically modifying the top layer of nanoparticles utilizing the functional surfactant molecules and applying a further layer of nanoparticles thereto.

摘要:
A radio frequency (RF) switch using a field effect transistor has 2nd order intermodulation distortion improved through use of a feed forward capacitor electrically connected between the gate and a voltage coupler connected between the source and drain of the FET. With a control voltage provided at the gate through a gate feed resistor for operation of the FET, the feed forward capacitor feeds an RF voltage from the drain terminal and the source terminal to the gate terminal through the gate feed resistor.

A method includes: providing a substrate having a plurality of chemically contrasted alignment features, and depositing a self-assembled material on at least a portion of the substrate, wherein the position and/or orientation of substantially spherical or cylindrical domains of the self-assembled material is directed by the alignment features, to form a nanostructure pattern, and wherein the period of the alignment features is between about 2 times and about 10 times the period of the spherical or cylindrical domains. An apparatus fabricated according to the method is also provided.
摘要:
Embodiments provide a switching device including one or more field-effect transistors (FETs) and bias circuitry. The one or more FETs may transition between an off state and an on state to facilitate switching of a transmission signal. The one or more FETs may include a drain terminal, a source terminal, a gate terminal, and a body. The biasing circuitry may bias the drain terminal and the source terminal to a first DC voltage in the on state and a second DC voltage in the off state. The first and second DC voltages may be non-negative. The biasing circuitry may be further configured to bias the gate terminal to the first DC voltage in the off state and the second DC voltage in the on state.
