  • Publication number: 20230140466
    Abstract: Disclosed are a negative transconductance device and a multi-valued memory device using the same. The negative transconductance includes a monolithic WSe2 semiconductor thin film; a first doped layer disposed on a first area of the WSe2 semiconductor thin film; a second doped layer disposed on a second area of the WSe2 semiconductor thin film so as to supply holes to the second area, wherein the second area is spaced apart from the first area; a first electrode electrically connected to the first area of the WSe2 semiconductor thin film; a second electrode electrically connected to the second area of the WSe2 semiconductor thin film; and a third electrode for applying a gate voltage to the first area and the second area of the WSe2 semiconductor thin film, and to a third area thereof located between the first and second areas.

  • Publication number: 20160268649
    Abstract: A battery pack is disclosed. In one aspect, the battery pack includes a secondary battery including at least a pair of electrode tabs and a circuit board accommodating at least one circuit configured to control charging and/or discharging operations of the secondary battery. The circuit board includes a bending portion and first and second portions respectively extending from opposing ends of the bending portion and at least partially overlapping and spaced apart from each other. The first portion includes a tab fixing surface configured to fix the at least pair of electrode tabs thereto, and the second portion includes a circuit fixing surface configured to fix the at least one circuit thereto. The tab fixing surface faces the second portion. The battery pack also includes an insulating plate placed between the tab fixing surface and the second portion, and contacts the at least pair of electrode tabs.
