Stability of Pd-MOSFET


Miscellaneous changes, resulting in V. s change. Fourth,[link widoczny dla zalogowanych], Development and Prospect: In recent years, I plant the MQ51-type hydrogen-sensitive sensor devices and use it as a variety of tying leakage, monitoring equipment, has been used to power (Power Transformer Fault Monitor, H | net generator monitoring Lie instrument, etc.), electronics (clean Q monitoring), gas manufacturing (hydrogen station monitoring guillotine), the public rejection of gas Jianlou other fields, and received a remarkable economic and social benefits. We think that such a device to further enhance the stability, reliability, will be more widely used. To produce a more stable, high-quality hydrogen-sensitive devices and other kinds of sensitive devices. In addition to the depth of research, but also must make the necessary technological innovation,[link widoczny dla zalogowanych], the use of advanced technology, equipment, the only way that Lou j-sensitive devices (MOS type) will have great hair References (1) I.

Danne-tun, \tin acid test is not used in a pre-burn and adding an appropriate amount of rare earth oxide additives such as waterfall, increasing the device on the selectivity and stability of ethanol vapor. Li hundred semiconductor gas devices are developed in the sixties a new type of sensitive device. It semiconductor surface by means of adsorption desorption gas I produced changes in resistance value to achieve the purpose of testing the gas. In recent years, semiconductor gas sensor devices have a great development at home and abroad, has been in the petrochemical, power generation , electronics and other industrial and household alarm widely used terms, so that sensing device into the practical stage. but the selectivity, stability,[link widoczny dla zalogowanych], consistency and production aspects of the quantitative detection far not been resolved. In order to improve air sensitive device performance, the researchers conducted a national research active and have achieved some results. by doping the semiconductor gas sensor devices help to improve the selectivity and stability. For example: doped oxides ThO CO gas sensing devices sn Hu has a good matchmaker on selective [1] j doped V: 0, Cu and rare earth SnO2 of hexanol with high sensitivity [2:. With the development of industry and agriculture, automotive transportation unprecedented peak, traffic accidents have occurred, traffic safety barrier become a very pressing issue. because of traffic accidents caused by drivers driving under the influence a large proportion of this, many units are in the development of the domestic production of alcohol and car alcohol detection self-locking devices to control the drivers drinking and driving and reduce traffic accidents. Therefore, the urgent need for good selectivity to ethanol gas sensitivity of semiconductor devices for its alcohol sensor. I started to develop the factory in 1987 as the base for semiconductor SnO Wine sensitive device. through a lot of experimental work, developed MQK2-I-type semiconductor alcohol sensor with a tesattheex0ernalandinternalpalladiumsurfaceofapalla-dium - sllicondioxide ~ siliconstructure.J.App1.Phys.58 (1) IJuly, P404 ~ 412,[link widoczny dla zalogowanych],1985.
