In this blog post, we’ll take a simple look at everything from what a semiconductor is—including its energy band structure and the principles of electrical conductivity—to the formation process of n-type and p-type semiconductors, as well as the various applications of semiconductors, such as diodes and transistors.   We often come across semiconductors in various media, such as newspapers...

In this blog post, we’ll examine the structure and operating principles of 3D transistors—which were developed to overcome the limitations of planar transistors—and explore how they have enhanced semiconductor performance and power efficiency.   There is an animated sitcom called “The Jetsons,” which first aired in 1962. In the show, the main character drives a flying car. He doesn’t need to...

In this blog post, we’ll explore the basic principles and evolution of semiconductors, the relationship between transistors and integrated circuits, advancements in LED and display technologies, and the future direction of semiconductor technology in the age of artificial intelligence.   People refer to the present as the digital age. It is also said that the Information Revolution followed...

In this blog post, we’ll explore everything from the basic principles of semiconductor devices to how transistors work and their evolution, as well as the limits of miniaturization technology and the future direction of semiconductor technology.   The majors in the Department of Electrical Engineering can be broadly categorized into communications, semiconductors, control systems, computer...

In this blog post, we will examine the process by which bacteria synthesize proteins based on genetic information stored in their DNA, as well as the mechanism by which antibiotics target this process to inhibit bacterial growth and survival.   Protein Synthesis in Bacteria People constantly consume food to survive. To eat, food must be properly prepared, and to prepare it, a cookbook is...

In this blog post, we look back at former President Park Geun-hye’s controversial view of history—which sparked debate ahead of the 18th presidential election in 2012—as well as the People’s Revolutionary Party incident and the Jeongsu Scholarship Foundation scandal, to examine responsibility toward history and attitudes toward the past.   Everyone has their own subjective perspective and...

In this blog post, we’ll examine the principles behind wheel lockup in cars and the difference between static friction and kinetic friction, and explore the structure and operating principles of the ABS braking system, which automatically replicates the braking actions of a skilled driver.   Imagine you’re driving on a rainy road and suddenly spot an obstacle. Naturally, you’ll hit the...

In this blog post, we’ll examine the characteristics and roles of basosomes formed during X-chromosome inactivation in mammals, as well as the principle behind the varying coat colors of mottled cats.   You’ve probably either owned a cat or dog yourself or seen friends and family members raising them. When these cats or dogs have litters, you can observe some interesting phenomena: for...

In this blog post, I’ll explore why people perceive classical music as difficult and highbrow, and discuss what significance classical music can hold amid evolving music platforms and the hectic lives of modern people.   “Classical music is difficult,” “Classical music is for the elite.” These are common perceptions people have about classical music. Yet, at the same time, people aren’t...

In this blog post, I’ll examine the free-rider problem that arises in team projects and, through this, consider whether there is a reason for selfish people to live righteously.   Most of us probably have memories of working on at least one group project during our school days. When we first think of group projects, we tend to have certain expectations. There’s a certain romanticized vision...
