Abstract:
Provided is an electronic device. The electronic device includes a first semiconductor layer and a second semiconductor layer sequentially stacked on a substrate and a source electrode, a gate electrode, and a drain electrode arranged on the second semiconductor layer. The electronic device further includes a field plate which is electrically connected to the source electrode and extends towards the drain electrode, wherein the field plate becomes farther away from the substrate as the field plate becomes closer to the drain electrode.
Abstract:
Provided is a semiconductor device. The semiconductor device includes a substrate including a cantilever configured to generate a flow of cooling media through dynamic movement, an active area on the substrate which an electronic device is provided on, an insulation layer disposed to be spaced apart from the active area on the substrate, a lower electrode on the insulation layer, a piezoelectric film on the lower electrode, and an upper electrode on the piezoelectric film.
Abstract:
A cost-cognitive base station apparatus, a cost-cognitive user terminal, and a cost-cognitive network method, in which by recognizing costs based on network congestion, a user may select and receive appropriate network services, thereby reducing telecommunication expenses and inducing the user to a less congested network, which leads to improved network management efficiency.
Abstract:
The present invention relates to smart glasses, and the smart glasses include: a frame mounted with lens; a pair of temples extended in one direction from both side ends of the frame so as to face each other; a rear camera mounted at an end of the temple and configured to photograph a rear image of a wearer; a display unit installed at one side of the lens and configured to display the rear image photographed by the rear camera; and a control device configured to control an operation of each of the constituent elements, thereby enabling a user to check a situation in the rear view without turning his/her head.
