I've started to learn English when I was at school. But our teacher used a very simple book and nothing else. For me it was very easy. Then I entered to a gymnasium where teacher used Longman book and it was much more difficult for me. It was a very big difference between gymnasium and my first school. I've begun afraid English lessons. That's why in university at our first English class I was very afraid. I was afraid to pass some test very bad, the worst on our course. When someone opened a door and asked who wanted to learn German from zero I was one of the first students who went with her.

Which countries do you think have soft power? Why? For example, South Korea has Korean Wave and it has changed country's image. A lot of people know about Jumong or Gangnam Style

I am a big fan of Netflix now. This days I am watching Lucifer. What about you? Do you like TV serials?

Hi! I'm from Ukraine, from a small town in a center part of Ukraine. It is a well-known railway station here and a lot of people works at railway. Near the town is a forest. I liked to go to the forest at any seasons.

Are there mistakes?
The topic of my research is generation-recombination processes in heterostructures with one-dimensional nanostructures.
A search alternative energy source is the one of the discussion questions. A lot of scientist try to find the best material and structure for solar cells. So, we decided to research one of the semiconductors - heterostructures InGaAs/GaAs.
We are studying semiconductors samples InGaAs\GaAs with nanowires and without them. The samples were grown by molecular beam epitaxy.
We have investigated J-V-dependencies. Also we have found and analized an ideality factor for this structures at first time. For more information about the recombination processes kinetic of photo-voltage was measured in the studied systems. And also photovoltage spectrum were studied.

Structures with one-dimensional quantum objects in intermediate band are promising for their application in solar cells and infrared photodetectors. So, heterostructures with InGaAs QWRs require more detailed study and research.
