半导体是一种的特殊的材料,它的导电性能介于导体和绝缘体之间,它的电阻比导体大得多,又比绝缘体小得多,在外界条件改变时,半导体有许多特殊的性能,在现代科学技术中被广泛的使用,为了引领中学生对半导体这些特性的了解和认识情况,与半导体相关的中考试题成为中考的一大亮点题型,这类试题具有涉及知识点多,综合性较强,所占分值高等特点,一般都是以压轴题的形式出现.为了引起同学 Semiconductor is a special kind of material, its conductivity between the conductor and the insulator, its resistance is much larger than the conductor, and much smaller than the insulator, the semiconductor has many special properties in the external conditions change, In modern science and technology has been widely used, in order to lead the students to understand these characteristics of semiconductor understanding and knowledge, and the semi-conductor test questions become a major highlight of the exam, such questions have more knowledge, more comprehensive than Strong, the higher scores, the characteristics are generally based on the finale title in order to arouse students
