摘要:
Inverter logic devices include a gate oxide on a back substrate, a first graphene layer and a second graphene layer separated from each other on the gate oxide, a first electrode layer and a first semiconductor layer separated from each other on the first graphene layer, a second electrode layer and a second semiconductor layer separated from each other on the second graphene layer, and an output electrode on the first and second semiconductor layers and configured to output an output signal. The first semiconductor layer is doped with a different type of impurities selected from n-type impurities and p-type impurities than the second semiconductor layer.

Graphene, a method of fabricating the same, and a transistor having the graphene are provided, the graphene includes a structure of carbon (C) atoms partially substituted with boron (B) atoms and nitrogen (N) atoms. The graphene has a band gap. The graphene substituted with boron and nitrogen may be used as a channel of a field effect transistor. The graphene may be formed by performing chemical vapor deposition (CVD) method using borazine or ammonia borane as a boron nitride (B—N) precursor.

Provided are a spin valve device including graphene, a method of manufacturing the spin valve device, and a magnetic device including the spin valve device. The spin valve device may include at least one of a graphene sheet or a hexagonal boron nitride (h-BN) sheet between a lower magnetic layer and an upper magnetic layer. The graphene sheet may have a single layer structure or a multilayer structure. The spin valve device may further include a spacer between the lower magnetic layer and the graphene sheet. The spin valve device may further include a spacer between the graphene sheet and the upper magnetic layer.
摘要:
Provided is a graphene device and a method of manufacturing the same. The graphene device may include an upper oxide layer on at least one embedded gate, and a graphene channel and a plurality of electrodes on the upper oxide layer. The at least one embedded gate may be formed on the substrate. The graphene channel may be formed on the plurality of electrodes, or the plurality of electrodes may be formed on the graphene channel.
摘要:
Live strains of Lactobacillus acidophilus HY2177 and Lactobacillus casei HY2743 maintained in nutritious foods, such as yogurt, imbue them with prophylactic and/or therapeutic properties. Such foods are beneficial in the prevention and/or treatment of gastritis, duodenal and gastric ulcers caused by infection from Helicobacter pylori (also referred to as H. pylori). The properties of these bacteria are boosted by the addition of egg yolk containing antibodies specific to H. pylori antigen derived from “fractionated H. pylori” and may be administered as active strains alone in a food supplement, or the active strains may be combined with H. pylori-antibodies (IgY).
