    • A thermoelectric module is constituted by a pair of substrates having electrodes, which are arranged opposite to each other with a prescribed space therebetween, in which a prescribed number of thermoelectric elements are arranged in such a way that a p-type and an n-type are alternately arranged, so that the thermoelectric elements are connected in series or in parallel together with the electrodes. Herein, one substrate is a heat absorption side, and other substrate is a heat radiation side. In addition, a current density in a current transmission area of the heat-absorption-side electrode is set to 50 A/mm2 or less, and a height of the thermoelectric element is set to 0.7 mm or less. Furthermore, a temperature-controlled semiconductor module can be realized by combining a thermoelectric module with a semiconductor component such as a semiconductor laser.

    • A field effect transistor includes a semiconductor substrate of a first conductivity having a source zone and a drain zone of an opposite, second conductivity spaced apart therein and extending to the surface thereof. A surface channel adjoins the surface, is of the second conductivity, and extends in an area located between the source and drain zones. A gate electrode is carried above the surface channel, either on an insulator, or directly on the surface to form a Schottky junction. A second zone lies beneath the surface below or in overlapping relation to the surface channel and extends between the drain and source zones. The second channel is doped with dopant particles whose energy level in the forbidden band of the semiconductor substrate, at an operating temperature T, lies at a distance of more than 1/2 kT from the conduction band edge and valence band edge of the semiconductor substrate. Application of proper potentials with respect to the start voltage required for ionization of the dopant particles in the second channel causes the field effect transistor to function as a high-speed switch. Connection of the field effect transistor in series with a resistance between the poles of a power supply which has a voltage greater than the start voltage causes the field effect transistor to operate, in combination with the resistor, as an oscillator.
    • 场效应晶体管包括具有第一导电性的半导体衬底,该半导体衬底具有源极区和漏极区,其间隔开并延伸到其表面。 表面通道邻接表面,具有第二导电性,并且在位于源极和漏极区之间的区域中延伸。 栅极电极在绝缘体上方或表面上直接承载在表面通道上方,以形成肖特基结。 第二区位于表面下方或与表面通道重叠的表面下方,并在漏区和源区之间延伸。 第二通道掺杂有掺杂剂颗粒,其在半导体衬底的禁带中的工作温度T处的能级与半导体衬底的导带边缘和价带边缘之间的距离大于1/2 kT 。 对于第二通道中的掺杂剂粒子的电离所需的起始电压的适当电位的施加使得场效应晶体管起到高速开关的作用。 与具有大于启动电压的电压的电源极之间的电阻与场效应晶体管的串联连接使得场效应晶体管与电阻一起作为振荡器工作。
