- Electromagnetic waves with waves shorter than radio waves and longer than red visible light rays are infrared rays. When infrared is irradiated on a matter and the transmitted or reflected light is studied, it is possible to obtain information about the bonding of the elements in the matter.
- Interfacial phase
- Although polycrystalline matter consists of many crystal grains, the interfacial phase refers to the phase (a domain that has a certain structure) that is formed in the narrow spaces in between these grains. In polycrystalline matter, the structure of the interfacial phase is often influenced by mechanical properties.
- Inverse spin-hall effect
- This is the phenomenon wherein electromotive force is generated in a direction perpendicular to the spin current. This is caused by the interaction between the electron spin and the orbit, which scatter electrons with an upward spin and electrons with a downward spin in opposite directions. This is important in spintronics as a phenomenon that connects spin information and electrical information.
- K (Kelvin)
- This is a unit of measure for temperature. Its relationship to Celsius degrees, a commonly used unit of measure for temperature, is expressed in the following formula.
- Lanthanum titanate
- This is a compound of titanium, lanthanum, and oxygen, and is expressed by the chemical formula LaTiOx (X: Oxygen composition). Lanthanum titanate that has lithium added to it is used as material for the creation of lithium batteries (electrolytes).
- Light-emitting diode
- This refers to a semiconductor device that emits light by applying an electric current to the junction of two semiconductors, such as p-type or n-type. The color of the light emitted changes depending on the material of the semiconductor. It is also known as LED.
- Logic integrated circuit
- A logic circuit in a computer is a circuit that converts (computes) input information into combinations of the two values of “0” and “1,” outputs this data, and processes it. In short, it is a circuit that returns actions and results in response to operations. A logic integrated circuit is built by placing (integrating) as many of these logic circuits as possible in as small a space as possible. Combining a large number of these logic integrated circuits creates the processor that serves as the “heart” of a computer, enabling the completion of complex computations (information processing) within a short period of time.
