Definitions
- the present invention relates to a transistor comprising three layers constituting, respectively, the base, the emitter and the collector, each of the latter two being provided with an electrode to enable it to be connected to an electric circuit.
- the transistor according to the invention is distinguished from known transistors by the fact that the said base is provided with two electrodes situated at different distances from the emittter, so that it is possible to connect the base to two independent electric circuits permitting of controlling the emitter current, means being provided for varying within wide limits, by means of the space charge zone due to the potential difference between the collector and the base, the electric resistance of that part of the base by means of which one of its electrodes is electrically connected to the emitter-base junction, without substantially modifying the resistance of that part of the base by which the other of its electrodes is electrically connected to the said junction.
- FIG. 1 is a view of a transistor according to a first constructional form, as seen from the emitter side.
- FIG. 2 is a section along the line 11-11 of FIG. 1.
- FIGS. 3 to 5 show in section three other constructional forms.
- FIG. 6 is a diagram of the application of the transistor.
- the transistor comprises in the usual manner a central semi-conductor layer, for example of n-type, which is intended to form the base B.
- a central semi-conductor layer for example of n-type, which is intended to form the base B.
- a p-type semi-conductor layer intended to form the emitter E and the collector C respectively.
- Each of the said three layers B, E and C is provided with an electrode b, e, and 0 respectively by means of which it can be con nected to an electric circuit.
- the electrode b is in the form of a ring surrounding the emitter E.
- a circular groove 0 surrounding the emitter.
- the base is provided with a second electrode 11,, also in the form of a ring.
- the electrodes b and b may be connected to different electric circuits, and the emitter current may therefore be controlled by two different control voltages.
- the electric resistance of that part of the base B which electrically connects the electrode b to the emitterbase junction may be varied by the voltage of the collector C within such limits that the control circuit of which it forms part can be substantially interrupted.
- the space charge zone due to the potential difference between the collector and the base is proportional to the square root of the collector voltage for a given base, the latter voltage may be made such that this zone extends as far as the groove 0, as indicated in chain lines in FIG. 2, and substantially breaks the circuit b-E. Since the part B of the base is not reached by the said zone, its resistance remains substantially unchanged, so
- a single transistor according to the invention can be used as a bistable multiifator, for example in accordance with the diagram of
- the collector C is connected through a resistance R to the negative pole of a direct-voltage source S.
- the positive pole of the source S is connected to the emitter E, which is earthed.
- the electrode b is negatively biased in relation to the emitter E by means of a source S
- the electrode b is positively biased in relation to the emitter E by means of a source S which is effected through a resistance R
- the electrode b is connected through a capacitor K to an alternating-voltage pulse generator I.
- the value of the latter is so chosen that the space charge Z0118 due to the potential difference between the collector and the base can extend as far as the groove 0 (shown in chain lines in the drawing), the value of the electric resistance of that part of the base which electrically connects the electrode b to the emitter-base junction will be practically infinite, so that the circuit bE will be practically interrupted. Owing to the positive biasing of the electrode b by the source 8,, the transistor will remain blocked even when the cause of the blocking, namely the positive voltage, has ceased.
- FIGS. 3 to 5 show three other constructional forms of the transistor according to the invention.
- the base 3 comprises a thickened portion B on which are disposed the emitter E and the electrode b It will readily be seen that the electric resistance of that part of the base which electrically connects the electrode b to the emitterbase junction can be varied by means of the space charge zone due to the potential difference between the collector and the base without modifying the resistance of that part B, which connects the electrode b; to the said junction.
- the transistor according to FIG. 4 comprises two ringshaped auxiliary collectors C and C one on either side of the base, and situated between the electrode b and b, of the base. These auxiliary collectors C and C are electrically connected to the main collector C.
- the electric resistance of that part of the base'which connects the electrode b to the emitter-base junction can here be varied by the space charge zones due to the potential differences between each of the auxiliary collectors and the base, which zones may extend one towards the other and even be joined together, without modifying the resistance of the part B connecting the electrode b, to the said junction.
- a part of the layer constituting the base B notably the part B on which the emitter and the electrode b are positioned, has a greater impurity content than the remainder of the base B.
- the electric resistance of that part of the base which is of lower impurity content and which connects the electrode b to the emitter-base junction may be varied by the space charge zone due to the potential difference between the collector and the base without the resistance of that part B of the base which has higher impurity content and which connects the electrode b; to said junction being substantially modified.
- the two electrodes b and b of the base are ring-shaped. It is obvious that they could have any other form.
