Abstract: In a transistor in which the majority carriers are holes, at least one narrow bandgap region or layer is doped p-type or contains an excess of holes and is subject to compressive mechanical strain, whereby hole mobility may be significantly increased. In a p-channel quantum well FET, the quantum well InSb well p-type layer 5 (modulation or directly doped) lies between In1-X A1X  Sb layers 4, 6 where x is of a value sufficient to induce strain in layer 5 to an extent that light and heavy holes are separated by much more than kT.  Transistors falling within the invention, including bipolar pnp devices, may be used with their more conventional electron majority carriers counterparts in complementary logic circuitry.

Abstract: The present invention refers to a novelty in the distribution of locking pins in locks and other systems that employ locking pins and unblocking keys that prevent the rotation of the wrong key. Additionally, they make the break-in action difficult.      The invention discloses a lock (1), provided with a rotating cylinder (2) receiving a key (3), the inner portion of the rotating cylinder (2) receives attenuating locking pins (4) that run supported by counter-locking pins inside grooves (6), being actuated by springs (7), in addition to one or more neutral pins (8) always positioned between the attenuating locking pins (4).       The neutral pin (8), under its normal condition, without being actuated by the key (3) or picklock (10), is aligned with the tangency line (9) of lock (1) and does not prevent, alone, the rotation of cylinder (2). Once a wrong key or picklock (10) is inserted into the rotating cylinder (2), the attenuating pins (4) are displaced so as to allow the rotation of cylinder (2) and the break-in of lock (1); however, the neutral pin or pins (8) are displaced downwards, crossing the tangency line (9), being actuated and preventing the rotation of cylinder (2) and the consequent break-in of lock (1).
