Low defect, high purity crystalline layers grown by selective deposition

The purity and perfection of a semiconductor is improved by depositing a patterned mask of a material impervious to impurities of the semiconductor on a surface of a blank. When a layer of semiconductor is grown on the mask, the semiconductor will first grow from the surface portions exposed by the openings in the mask and will bridge the connecting portions of the mask to form a continuous layer having improved purity, since only the portions overlying the openings are exposed to defects and impurities

Method for growing low defect, high purity crystalline layers utilizing lateral overgrowth of a patterned mask

A method for growing a high purity, low defect layer of semiconductor is described. This method involves depositing a patterned mask of a material impervious to impurities of the semiconductor on a surface of a blank. When a layer of semiconductor is grown on the mask, the semiconductor will first grow from the surface portions exposed by the openings in the mask and will bridge the connecting portions of the mask to form a continuous layer having improved purity, since only the portions overlying the openings are exposed to defects and impurities. The process can be iterated and the mask translated to further improve the quality of grown layers

Efek Udara Di Dalam Sistem Refrigerasi

The performance of refrigeration system are affected by condenser, evaporator ,compressor and regulating valve. Besides cooling system itself air in the system are also considered to the performance. The aim of this research to investigate the effect of air in the refrigeration system that cause the performance of system. The result of this research indicates that coefficient of performance (COP)decrease falls to 37 % (from 8.4 to 5.28) due to the air in refrigerations system, on the contrary there is increasing about 40 % (from 25 kJ/kg to 35 kJ/kg)of energy in gernerating compresso

Pengaruh Penerapan Model Pembelajaran Dan Motivasi Belajar Terhadap Hasil Belajar Siswa Pada Mata Pelajaran IPS Di SMP Negeri Model Terpadu Madani Palu

This research aims at identifying the differences in the learning achievement between students who were taught by using the ASSURE learning model to those whom were taught by using conventional learning model; interaction between learning model and learning motivation; the difference between learning achievement of high and low motivated students. The sample of this research is Chairil Anwar VIII grade consisted of 28 students as the control class. The design of this research is quasi experiment 2 x 2. The treatment variable is learning model and the attribute variable is learning motivation, while the dependent variable is the learning achievement of Social Sciences subject. The hypothesis was tested through ANAVA two ways with different cells to significant level of 5%. The result of the differences between ASSURE model learning achievement and conventional proven by the score of statistic test where Fcounted = 7.084 and Ftable = 5.79 or Ho is rejected. It means that there is difference between learning achievement of ASSURE class to the conventional class. The score of statistic test where Fcounted = 25.27 and Ftable = 5.79 or Ho is rejected. It means that there is difference between group of high motivated students and group of low motivated students. The score of statistic test between motivation and learning model where Fcounted = 0.010 and Ftable = 5.79 or Ho is accepted. It means that there is no interaction and affect to the learning achievement between learning model to learning motivation

Pemahaman Masyarakat Tentang Kekerasan Seksual pada Anak di Kupang

Kekerasan seksual terhadap anak terlihat semakin marak kasusnya, karenanya diperlukan informasi sampai sejauh mana pemahaman masyarakat tentang kekerasan seksual dimaksud, khususnya yang dilakukan oleh orang-orang terdekat (incest), yang dampaknya membawa trauma serius dan berkepanjangan bagi korban anak yang mengalami kekerasan seksual ini.
