On June 2, according to the official Weibo of the Chinese Academy of Sciences, the team of Shi Xun, a researcher at the Shanghai Institute of Ceramics, Chinese Academy of Sciences, and Chen Lidong, an academician, and the team of Professor Wei Tianran of Shanghai Jiaotong University, found that a special type of brittle semiconductor has good plastic deformation and processing ability at 500K, and established Yon tanperati ki gen rapò ak plastik modèl fizik, reyalize yon metal-tankou pwosesis pwosesis plastik nan semi-kondiktè, ki bay sipò enpòtan pou anrichisan inòganik semi-conducteurs pwosesis ak manifakti teknoloji ak agrandi senaryo aplikasyon . rezilta yo rechèch ki enpòtan yo te pibliye nan lanati-Materyèl .}
The report mentioned that semiconductor materials have rich and adjustable functional properties, but the processing cost at room temperature is high and the process flow is complex, relying on a series of fine preparation and precision processing technologies. In recent years, researchers have successively discovered some inorganic semiconductor materials with room temperature plasticity at the macroscopic scale, but the types of semiconductor materials with room temperature Plastisite yo toujou trè ra, ak pwopriyete yo fizik pa ka satisfè bezwen an aplikasyon lajè nan endistri a semi -conducteurs . Ekip la rechèch te jwenn ke yon seri de tipik bandgap etwat inòganik semi -kondiktè ka sibi plastik "cho pwosesis" tankou woule woule, plat yo, ak èkstruzyon nan kondisyon yo ki pi wo a, epi yo te manje a.
Yon seri de eksperyans te pwouve ke metòd la plastik pwosesis cho gen avantaj nan manifakti-wo kalite fim semi-conducteurs, ki ka evite restriksyon ak divès kalite depans adisyonèl te pote pa substra a; Ka epesè nan fim dwe lib ajiste nan seri a nan mikron milimèt; Fim nan gen bon kristalinite ak distribisyon eleman inifòm, epi li eritye pwopriyete yo ekselan ak reglabl fizik nan analiz la esansyèl . analiz microstructural montre ke deformation an plastik nan materyèl sa yo nan yon ti kras pi wo a tanperati chanm se sitou ki te koze pa deformation reorganizasyon grenn jaden yo ak yon pwopòsyon Torsion Torsion {{{{ Tanperati tranzisyon ductile-bittle nan materyèl inòganik ki pa metalik, ak konklizyon yo ki konsistan avèk done eksperimantal .
The research team said that the high-performance self-supporting semiconductors obtained by the plastic warm processing method have broad application prospects in electronic and energy devices. Taking thermoelectric energy conversion as an example, the research team selected rolled sheets of three high-performance thermoelectric materials and developed two out-of-plane thin-film thermoelectric Aparèy . Maksimòm dansite pouvwa normalized nan de aparèy yo se sou de fwa sa yo ki an menm jan ak aparèy tèrmo-fil tèmik deja rapòte .
