Bu çalışmanın amacı, yoğun lazer alanı altında üçlü ters parabolik kuantum bariyer çift kuyu potansiyelinde elektronik iletim ve enerji seviyelerinin bariyer genişlikleri, lazer alanı giydirme parametresine bağlılığını araştırmaktır. Çalışmada Denge-dışı Green fonksiyonları yöntemi kullanılarak iletim olasılıkları ve rezonans enerji seviyeleri tespit edilmiştir. Lazer alanının ve yapı parametrelerinin rezonans tünellemeyi oldukça etkilediği, enerji seviyelerinin yerlerinin kontrolünün bu parametrelerle yapılabildiği görülmüştür. Lazer alanının artmasıyla enerji seviyelerinin daha yüksek enerjilerde ortaya çıktığı görülmüştür. Yapının rezonans tünelleme özelliğinin kontrolü işlevsel nano-aygıt yapımında oldukça önem arz etmektedir.

Investigation of Relation of Electron Transmission and Energy State to Structure Parameters and The Intense Laser Field in The Triple Inverse Parabolic Quantum Barrier Double Well Potential

Öz

The aim of this study is to investigate the dependence of the transmission properties and energy state of the triple inverse parabolic quantum barrier double well potential under the intense laser field with the well and barrier widths and the laser field dressing parameter. In the study, transmission probabilities and resonance energy levels were determined using the Non-Equilibrium Green functions method. It has been observed that laser field and structure parameters affect resonance tunneling and control of the location of energy levels can be done with these parameters. It has been observed that energy levels emerge at higher energies as the laser field increases. The control of the resonance tunneling feature of the structure is very important in the production of functional nano-devices.
