Title: One-dimensional channel field effect transistor by application of magnetic field
Inventor: YAMADA TOSHISHIGE
IPC: H01L29/06
Filed: 1987-12-25
Abstract: PURPOSE:To obtain electrons of one-dimensional conducting state and to improve moving difference by applying a magnetic field in which electron cyclotron vibration energy in channel is sufficiently larger than lattice temperature in the source.drain direction. CONSTITUTION:When a magnetic field is applied by a magnetic field applying device 5 to a transistor 1, electrons in the transistor 1 are quantized in kinetic energy perpendicular to the magnetic field, and the energy is represented by an equation E=(n+1/2) homegaC+(hK)<2>/2m*. In the equation, n is the number of quantums indicating the Landau level, omegaC is the frequency of a cyclotron and represented by eB/m* with a magnetic field B. K is the number of waves of electrons in the direction of the magnetic field. If the magnetic field is sufficiently strong and the condition of homegaC KBT is satisfied as compared with temperature KBT, most electrons have the level of n=0 in a weak magnetic field, thereby becoming an one-dimensional electron system. In this case, the state density P(E) of the electrons has dependency of minus one-half power of the energy. Accordingly, high mobility conduction of the one-dimensional electrons occurs. When a semiconductor material is of magnetic gallium, its temperature is reduced to 10-100 deg.K, and a magnetic field of 10-100T may be applied.

Filed: 1990-11-28
Abstract: PURPOSE:To execute more efficient encoding as a whole by allotting more code quantities by further reducing step sizes for a boundary block and reducing the code quantities by correspondingly enlarging the step sizes in the region of other flat parts or fine parts.

A selector 88 is set in a 1st or 2nd state and selects the maximum or minimum value. The value given from the group or the prescribed value is selected as the extreme value based on a flag 84 that is set through the comparison carried out via the unit 26 and the selector 88. Meanwhile, the prescribed value is replaced with the extreme value and the count value of the register 100 is stored when the value given from the group is smaller than the prescribed value. Thus, it is possible to specify the maximum or minimum value of accumulation cost when the received digital signals undergo the Viterbi decoding.
