Major Field:
Semiconductor Material Engineering
Field of Research:
Semiconductor Energy Material (Thermoelectric Material / Solar Cell 
Material) ‘Environmentally Friendly’ Semiconductor Material
Research Content:
Due to mass consumption of fossil fuel and also for prevention of global warming, research and development of energy conversion materials are being conducted. Solar energy being the main source of reusable energy, development of solar cell material and thermoelectric conversion material is being conducted. Due to the fact that many elemental devices which are used for energy conversion tending to be toxic, development of environmentally benign semiconductor energy material continues to be conducted. Environmentally benign semiconductors are composed of semiconductor material which abundantly exists on earth and is highly ‘earth-friendly’.

Diversity of Species 
According to a research paper by Dalhousie University, Canada, and Hawaii University, USA, published on 24th August 2011, there are more than 8.7 million biological species on earth(*). Of these, an incredible 100 species become extinct every day. Human beings, who are just one species of animal, damage the global environment on a large scale, rapidly destroying the ecological system and causing many living creatures to disappear in many parts of the world. If this trend were to continue, in 25 years, about a quarter of the biological species currently inhabiting the earth would become extinct.

Human beings may possess higher levels of intelligence compared with other creatures; however, human beings are just one kind of biological material that is part of an ecological chain.  If, in the future, the chain is destroyed human beings cannot survive as a species.  Therefore, we must protect the global environment on a worldwide basis.
Climate Change, Carbon Dioxide, and Responsibility
Every year, the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP) talk about reducing the amount of greenhouse gases (CO2) emitted. Greenhouse gases are a major cause of global climate change.  However, whereas the industrialized nations demand that all nations should control CO2 emissions, the developing countries insist that the amount should depend on their level of economic development which differs greatly between nations.  Meanwhile, detailed research has revealed that carbon dioxide levels clearly increased in the 1800s, the period of the Industrial Revolution, and after the 1950s, the period of postwar growth.  This means the CO2 concentration in air we currently consider as a problem is due to emissions made in the past by industrial countries and this has caused the current global climate change.  Our present affluence owes much to the already emitted carbon dioxide.
 Recycling of Waste Heat
In our laboratories, we have been making efforts to reduce CO2 emissions in order to make amends for our past responsibilities and to promote future harmonious coexistence with nature and with the various peoples in the world. Fossil fuels, oil, coal and natural gases are easy to handle.  However, as well as emitting carbon dioxide gases, 70% of fuel is wasted as waste heat.  On a worldwide scale, an enormous number of industrial furnaces and internal combustion engines have been producing ‘waste heat’.  Now, by combining scientific knowledge (physics and chemistry) with mathematics, our laboratories have been developing projects that promote the idea that wherever there is waste heat, it can be changed into a source of power.
How we should proceed
In order to play even a small roll in addressing large-scale environmental issues, it is of course necessary to focus our whole energy on it. Furthermore, we need to think about the direction we must take and to learn about the world and different cultures. Moreover, we must discuss these issues with many people. Those who have accomplished many great things in the past can provide us with valuable advice.  Their words can have a profound affect on us and will help us make the right decisions. They will help determine the way in which we should go and inspire us at decisive moments.
There is one thing we do know: that we are here for the sake of each other - above all for those upon whose smile and well-being our own happiness depends, and also for the countless unknown souls with whose fate we are connected by a bond of sympathy. 
Albert Einstein  (1879 - 1955)
Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
Steve Jobs  (1955 - 2011)
We can learn a lot from nature in action.
We keep moving forward opening up new doors and doing new things.
I feel every person creates his own ‘determinism’ by discovering his best aptitudes and following them undeviatingly. You are only as good as your next picture. If you can dream it, you can do it.
Walter Elias Disney  (1901 - 1966)
Sometimes to take a major step forward, we have to completely change direction.
