摘要： PROBLEM TO BE SOLVED: To increase a potential barrier in the case of application to a quantum effect device, by using supper lattice structure wherein first thin films formed by oxidizing or nitriding or oxidizing and nitriding semiconductor containing specific elements and second thin films made of semiconductor are alternately formed. SOLUTION: After a buffer layer 12 is grown on a substrate 11, supper lattice structure 15 is formed by repeatedly growing well layers 14 and barrier layers 13 containing Al as constituent element, in the respective thicknesses. A P-type layer 16 is crystal-grown in a specified thickness, and then the barrier layer 13 is oxidized. The interface of supper lattice structure having an oxidized or nitrided barrier layer becomes sharp. The energy gap of an oxidized or nitrided layer remarkably widens, so that the barrier layer also becomes high. As a result, the second quantum level is sufficiently isolated, and resonance tunnel effect, quantum effect, etc., remarkably appear at a room temperature and a high temperature.

摘要： PURPOSE:To enable a compound semiconductor layer to be deposited with high quality and with good reproducibility, by supplying arsine (AsH3) or SbH3 to a growth system before depositing indium phosphorus on a silicon substrate by means of a vapor growth method. CONSTITUTION:An Si substrate is introduced into an MOCVD(metal organic chemical vapor deposition) apparatus, wherein it is cleaned within the atmosphere of hydrogen gas by heating the same. AsH3 gas is then supplied into the MOCVD apparatus for several to ten minutes. After the supply of AsH3 gas, supply of PH3 gas is started in tern. Thereafter, supply of TMI(trimethyl indium) is also started so that a first layer of InP is deposited. The Si substrate on which the first layer has been deposited in heated and TIM gas is again supplied to deposit a second layer of InP until a thickness of the second layer reaches a predetermined value. In this manner, layers having desirable crystallinity and specular properties can be realized with good reproducibility.

摘要： PURPOSE:To provide an accurate reflectivity measurement method and instrument by accurately measuring a sample with a high reflectivity. CONSTITUTION:Light from a light source 1 is branched into two light waves of a measurement wave (s) and a reference wave (r) and is chopped so that the light waves are in opposite phases at a frequency f1. Further, light for reference is chopped at a frequency f2 which is different from the frequency f1, the light is transmitted through a reflection mirror 17 with 90% reflection factor, and the transmitted light is received by one zero-point adjustment light reception element 19. The value is adjusted to be zero by light attenuators 13 and 14, light reflected by the reflection mirror is received by one light reception element through a standard sample and a measurement sample, and then a signal with f1 as a signal component and that with f2 as a reference signal are measured. The signals are processed by a division operator.
