电子波函数通过分子成键和反键态的不对称传播
Asymmetric propagation of electronic wave function through molecular bonding and anti-bonding states
摘要：
分子桥的电子输运表现出新颖的量子特性。电子波函数通过分子桥的传播与两个接触之间采用的单个原子桥完全不同。在分子桥的情况下，电子波传播子通过分子成键态和反键态干扰和影响传导，本文通过简单的计算表明，电子波传播子的干扰导致电子波通过成键态和反键态的不对称传播。而对于类氢分子，这些传播子对成键态的干涉是相消的，对反键态的干涉是相长的，使得反键态的谱函数只有一个峰。
英文摘要：
Electron transport through molecular bridge shows novel quantum features. Propogation of electronic wave function through molecular bridge is completely different than individual atomic bridge employed between two contacts. In case of molecular bridge electronic wave propagators interfere and effect conduction through molecular bonding and anti-bonding states.In the present work i showed through simple calculation that interference of electronic wave propagators cause asymmetric propagation of electronic wave through bonding and anti-bonding state. While for hydrogenic molecule these propagators interfere completely destructively for bonding state and constructively for anti-bonding state, giving rise to only one peak in spectral function for anti- bonding state.
