It's May when I stepped on the threshold of summer. The air brushing against the sleeves gradually warms up, and the world prepares for its bluest light. Even the noise of passers-by outside the window is as cheerful as the rhythm of the ball bouncing over the badminton racket. In May, a season of longing and unfamiliar moments, I met Dr. Pawan Kumar Srivastava, a researcher from India who is warmer than May.
▣ Please introduce yourself.
My name is Pawan Kumar Srivastava, 35 years old from India. I work as a postdoctoral researcher in the lab of Professor Lee Chang-gu of the Department of Mechanical Engineering at Sungkyunkwan University's Natural Science Campus. I think my passion for physics led me to my life as a researcher at Sungkyunkwan University's mechanical engineering department. After completing my master's degree in physics, I was convinced that I should build a career in science. So as soon as I finished my Ph.D. at Jawaharlal Nehru University in New Delhi, India, I went to Europe to start my research at the Budapest Institute of Technology and Economics in Hungary. I have a great affection for traveling as well as physics. I used to travel to more than 25 countries and explore new places, history, and culture until I was established at Sungkyunkwan University in mid-2017.
▣ What was the place you stayed before you came to Korea?
A small city called Gorakpur in Uttar Pradesh, India, is where I was born. It is about 800km east of New Delhi, the capital of India. Uttar Pradesh is the fourth largest area in India, and it is also home to the largest population in India as it has a large land. It has a population of about 200 million, so about four times the Korean population lives in this area. India is a textbook of 'integration of diversity'. India embraces various religious/cultural groups, and there are about 20,000 languages spoken nationwide. This cultural diversity naturally created various food cultures. In India, you can enjoy various traditional foods regardless of where you visit. Maybe that's why India is a very popular country with food-loving travelers. As you all know, there are many unique places in India. Taj Mahal, Red Port, the fortresses of Rajasthan. If you visit these various places in India, you can't help but fall in love with India.
▣ Is there any reason why you chose Korea among other countries?
Since I study science, I thought a healthy and safe working environment is more important than anything else to achieve good results in the field. Before I came to Korea, I talked to Professor Lee Chang-gu of Sungkyunkwan University during my stay in Europe, and he answered very kindly. I thought you would help me a lot in my research. The professor promised to provide a good research environment and said he would help me do free research. So I decided to go to Korea and visited Korea for the first time in February 2017. Before coming to Korea, many of my friends gave me a worried look, asking me if I would think about going to Korea again. I've heard a lot that it's hard for foreigners like me to adapt (from my friends' point of view) because Korea is a closed country (culturally closed country. Maybe that's why I was worried if I could adapt well when I first came to Korea. However, as I stayed at Sungkyunkwan University, I found that I was completely wrong. Korea is a place where everyone can feel full of love. So these days, I am very satisfied with my life in Korea. I became fond of Korean food and culture. I'm very satisfied with living with my wife, feeling the emotions of Korea.
▣ It's been 4 years since you came to Korea, have you ever traveled to Korea?
Yes, of course. After arriving in Korea, I traveled to big cities such as Seoul, Daejeon, and Busan. I went to many travel destinations such as Mt. Seorak, Ganghwado, and Jeju Island. Traveling from Seoul, a large city where global urbanization took place, to hiking trails on Seoraksan Mountain and caves on Jeju Island, I thought that Korea was a country that preserved its original nature well and achieved balanced modernization. I think this proper fusion with nature, tradition, and modern culture is what makes many travelers love Korea.
▣ What has changed in your life in Korea since the Covid-19 incident?
Covid-19 has affected our lives a lot since early 2020, and many parts have been ruined, but I think we're still maintaining our daily lives. The biggest change in the world is that (due to Corona 19) we can't travel freely, it's hard to meet many people, and many students are having difficulties in their studies. I couldn't leave the country even though I had to go to India. First of all, from the perspective of living in Korea, I think the government is doing its best under the responsibility of protecting the people after this incident. Thanks to this government effort, researchers like me could continue their research.
▣ Did you know about Sungkyunkwan University before you came to Korea?
I came to Sungkyunkwan University for the first time in 2017, and Sungkyunkwan University had a high ranking and good thesis performance, so I knew a little about Sungkyunkwan University before I came to Korea. I learned about Sungkyunkwan University in earnest when my Indian colleague started researching at Sungkyunkwan University in 2013. In addition to the reputation of the university, the atmosphere of the lab and the professor are very important, and I heard a lot about Professor Lee Chang-gu from my Indian colleagues who work at Sungkyunkwan University. Even my colleagues at other universities talked about Professor Lee Chang-gu. So I decided to do research at Sungkyunkwan University.
▣ Please tell us about the new technologies you've developed through this study.
Recently, our team published a study in Nature Electronics based on electronic tunneling by 'twisted homologous bonding'. Here, 'twisted homologous bonding' means that the electron transport channel consists of only one material, and a specific layer of material rotates mechanically with each other. The electronic devices we presented in our study work as resonance tunnel diodes stacked in three layers through the anisotropy of the black lin. This resonant tunnel diode is a high-frequency processing device that creates a quantum well in the middle of the path where the charge travels and moves the charge rapidly. This discovery is very significant in the field of security, non-destructive testing techniques, and medical imaging devices. We can see objects safely without harmful radiation such as X-rays. It is expected to be applied to various innovative technologies such as wireless communication, cancer diagnosis, new drug development, and ultra-fast image processing.
▣ What would you like to do if you finished your research?
If I finish my Ph.D. course for 5 years, I would like to work as an assistant professor in the near future. My goal is to contribute greatly to the development of engineering technology in India while working for a good research institute.
