The transmission of wave packets through tunneling barriers is examined using quantum molecular dynamics to accurately analyze the process. The objective is to determine the distribution of arrival times for tunneling packets as they cross barriers, alongside the momentum distribution of these packets. This study calculates the significant factors, including the average position and momentum of wave packets and their variances. The methodology incorporates intricate modeling of wave packet behavior when faced with Gaussian barriers, allowing observation of critical characteristics such as reflection and momentum shift. Results reveal that a fraction of the packet reflects back, while the average transmitted momentum and its variance undergo notable modifications due to barrier interaction. This behavior underscores the relevance of tunneling time in nanostructures, especially its influence on semiconductor response times to laser-induced packet generation near tunneling barriers. Overall, the findings provide valuable insights into tunneling phenomena that are essential for advancements in nanoelectronics and related technologies.
