브로민화 수은 (I)(Hg₂Br₂) 자체 확산 물리적 증착법 공정에서 자체 확산 전달현상 연구에서 얻어진 결론은 10-3≤g0≤g≤1g0 영역에서는 열 대류현상이 지배적이며 , g=10-4g0 영역에서는 대류에서 확산영역으로 전이되는 영역이며, 10-6g0≤g≤10-5g0 영역에서는 확산모드가 지배적이다. Hg₂Br₂의 총 몰플럭스는 중력가속도의 레벌 (level)이 1/10 크기로 감소함에 따라 기하급수적으로 감소함을 나타내고 있다는 것이다. 10°C≤ΔT≤50°C의 온도차 범위에서는 온도차 (ΔT)와 Hg₂Br₂의 총몰플럭스에 대한 관계식은 선형적으로 직선적 비례관계성을 보여주고 있다.
Abstract
During the Hg₂Br₂ physical vapor transport process with self-diffusion, it is concluded that for 10-3≤g0≤g≤1g0 the thermal buoyancy driven convection is dominant in the vapor phase; at the gravitational level of g=10-4g0, the transition region from the convection to diffusion occurs; for 10-6g0≤g≤10-5g0, the diffusion mode is predominant. The total molar flux of Hg₂Br₂ decays exponentially with the decreasing of one tenth of gravitational magnitude. For 10°C≤ΔT≤50°C, the total molar flux increases linearly and directly with the temperature difference between the source and crystal regions.
