Subject matter disclosed herein may relate to correlated electron switches that are capable of asymmetric set or reset operations.

The inventive concept provides MIT devices molded by clear compound epoxy and fire detecting devices including the MIT device. The fire detecting device is supplied with a power source from a power control device. The fire detecting device includes a MIT device including a MIT chip molded by a clear compound epoxy, a diode bridge circuit supplied with the power source from the power control device for providing a non-polar power source, a notice circuit supplied with the non-polar power source from the diode bridge circuit for warning of a fire alarm in response to a detecting signal from the MIT device, and a stabilization circuit for maintaining the detecting signal for a certain period.

Subject matter disclosed herein may relate to programmable current for correlated electron switches.

Tunneling field effect transistors (TFETs) including a variable bandgap channel are described. In some embodiments, one or more bandgap characteristics of the variable bandgap channel may be dynamically altered by at least one of the application or withdrawal of a force, such as a voltage or electric field. In some embodiments the variable bandgap channel may be configured to modulate from an ON to an OFF state and vice versa in response to the application and/or withdrawal of a force. The variable bandgap channel may exhibit a bandgap that is smaller in the ON state than in the OFF state. As a result, the TFETs may exhibit one or more of relatively high on current, relatively low off current, and sub-threshold swing below 60 mV/decade.

A technique relates to a semiconductor device. First metal contacts are formed on top of a substrate. The first metal contacts are arranged in a first direction, and the first metal contacts are arranged such that areas of the substrate remain exposed. Insulator pads are positioned at predefined locations on top of the first metal contacts, such that the insulator pads are spaced from one another. Second metal contacts are formed on top of the insulator pads, such that the second metal contacts are arranged in a second direction different from the first direction. The first and second metal contacts sandwich the insulator pads at the predefined locations. Surface-sensitive conductive channels are formed to contact the first metal contacts and the second metal contacts. Four-terminal devices are defined by the surface-sensitive conductive channels contacting a pair of the first metal contacts and contacting a pair of the metal contacts.

A method and system for designing and providing sustainable performance instruments. A new type of financial instruments called Sustainable Performance Instruments (SPI) provides investors with returns tied to the actual performance outcomes or impacts from a sustainable social or environments program or other policy interventions. The SPI incentivize investors with higher returns and/or borrowers with lower rates based on a scale on social and/or environmental and/or other objectives. The SPI are a new way to fund innovative projects in public and private sectors that may not be able to find financing or funding using conventional mechanisms. The SPI hold executors of the project or program accountable by directly tying financial returns and other benefits to actual measurable performance benchmarks or observable impacts.
