本研究基于合作的收益和风险,利用1980年—2017年的美国医药发明专利数据进行实证分析,探索发明人外部合作网络对核心技术和颠覆性技术形成的不同影响。研究表明,发明人外部直接合作对核心技术和颠覆性技术的形成均存在“倒U型”作用,但效果有所差异:在达到最优外部直接合作数量(“倒U型”拐点)之前,外部直接合作对核心技术的正向作用强于对颠覆性技术的正向作用,达到最优合作数量(“倒U型”拐点)之后,外部直接合作对核心技术的负向作用强于对颠覆性技术的负向作用;发明人外部间接合作对核心技术的形成存在负向作用,对颠覆性技术的形成存在正向作用;外部间接合作会减弱外部直接合作与核心技术的“倒U型”曲线关系,增强外部直接合作与颠覆性技术的“倒U型”曲线关系。研究结论从合作的收益与风险视角为管理者有效利用发明人外部合作网络来促成不同类型技术创新的产生提供决策参考。

Dear.Editor.This letter.pr.sents an impr.ved r.petitive contr.ller.Ir.) that uses a complex-coefficient filter.to enhance the tr.cking per.or.ance of a system for.per.odic signals. Compar.d with the low-pass filter.used in the conventional r.petitive contr.ller.Cr.), the complex-coefficient filter.causes less change in the phase and amplitude of a signal at the fr.quencies of the per.odic signal, especially at the fundamental fr.quency, when the two filter. have the same cutofffr.quency.

The ther.al stability of high-K dielectr.cs on Si is cr.tical in avoiding the malfunction of metal oxide field effect tr.nsistor. （MOSfET） in devices. Ser.es of annealing exper.ments have been per.or.ed to investigate the ther.al stability of atomic layer.deposited （ALD） lanthanum aluminate （LAO） thin films, a pr.mising amor.hous high-K candidate. The abr.pt inter.ace between LAO and Si r.mains intact at temper.tur.s below 600 ℃. Above this temper.tur., a SiO2-r.ch inter.acial layer.begins to appear.and thickens at higher.temper.tur.s. At 900 ℃, the inter.ace is r.ughened due to the for.ation of nano sized cr.stal nuclei above the inter.acial layer. which indicates the inter.acial r.actions with the Si substr.te. The ther.al stability of ALD AI203 thin films on Si have also been studied under.similar.conditions. The AI203/Si inter.ace r.tains its smoothness even after.full cr.stallization. This compar.son suggests that the r.r. ear.h element may catalyze the inter.acial r.actions. fur.her.annealing exper.ments on LAO films with differ.nt thickness end with a capping layer.show that the oxygen sour.e of the inter.acial layer.mainly comes fr.m the ALD oxide films.
