چکیده

در این مقاله روش نوینی برای توصیف فیزیکی ناحیه فضایی بار در یک دیود صفحه‌ای ارائه شده است. با توجه به این که در این روش از رویکرد حوزه زمان استفاده شده است، رفتار گذرای مسئله قبل از رسیدن به حالت پایدار به عنوان نتیجه‌ای از روش قابل دسترسی است. با فرض ورود الکترون‌ها با سرعت اولیه صفر، توزیع پتانسیل و جریان به دست آمده از این روش تطابق کامل با نتایج دیگر محققان دارند. همچنین، اعمال روش برای ورود الکترون با سرعت غیرصفر نیز نتایجی موافق با کارهای قبلی دارد.

چکیده [English]

A novel and rather simple method is presented to describe the physics of space-charge region in a planar diode. The method deals with the issue in the time domain and as a consequence transient time behavior can be achieved. Potential distributions and currents obtained using this technique, supposing zero initial velocity for electrons, reveal absolute agreement with Child's results. Moreover, applying the method for non-zero uniform initial velocity for electrons, gives results which are in good agreement with previous works
