Adsorption-controlled growth of Ga2O3 by suboxide molecular-beam epitaxy

Ga2O3 films have been grown at rates exceeding 1 um/hr with excellent smoothness (< 1 nm rms on 4.5 um film) and crystallinity at low temperature (575 °C) by a new variant of MBE called suboxide MBE.

This paper introduces a growth method—suboxide molecular-beam epitaxy (S-MBE)—which enables a drastic enhancement in the growth rates of Ga2O3 and related materials to over 1 μm h−1 in an adsorptio...

Additional in my present research results- I can take the resolution that- A New Universe to Explore Alone Over 30 years alone free researching in my Library without help of government. Finally- found out fulfillment Universe Creation, Creator & Cosmology discoveries everything. It’s finding from own theories with philosophy of Science and natural way to understood real history of the Universe & Cosmology. Correct Understanding (No need equation) Scientists, Researchers, Philosophers, Teachers, Students, Priests, Minded people, Generations & Observatory Scientists found- Education innovates- understanding the Universe & Real Cosmology with Infinite and Infinitesimal. A New Universe to Explore Alone: See into- URL’s pages: In order of merit- found realism- Who is the right one for World frontal & World fore-knowledge of astronomy, astrophysics & Cosmology with Infinite and Infinitesimal! At: https://www.linkedin.com/pulse/new-universe-explore-alone-shahidur-rahman-sikder/?published=t Finally a question may be arisen that- If Allah/God created everything, who created Allah/God? In that question there is no answer because it is not possible to take back our imagination power before it. So it is only one answer of this question that the power himself is standing behind it. The most important tale is that- The God does not exist but we found the Allah/God Partially.
WHY THE SPEED OF LIGHT AND FALLING OBJECTS PROVE THAT ELECTROMAGNETISM/ENERGY IS GRAVITY: Consider what is THE SUN, the orbiting PLANETS, AND then what is the SPEED OF LIGHT (c, A POINT). Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. This is PROVEN by F=ma AND E=mc2. E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED ELECTROMAGNETIC/GRAVITATIONAL FORCE/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THEREFORE, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent WITH/AS F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Consider the RELATION of photons AND THE SUN. NOW, it IS explained why objects THEN fall at the SAME RATE (neglecting air resistance, of course) AS WELL; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! IT IS CLEARLY PROVEN. Very importantly, outer "space" involves full inertia; AND it is FULLY INVISIBLE AND black. By Frank DiMeglio
DrCatherine Demetriades has given the below writing the thumbs up on her page. Here is an HONEST and extremely sharp physicist who can really think. She also added: "This is why we say a picture speaks a thousand words." Great. IT'S ALL CLEARLY CORRECT. Mr. Shashi Singh (an excellent instructor of physics who is honest) has given the below writing the thumbs up. Moreover, he wrote: "Awesome !" and "Absolutely right." Excellent !!! It's all clearly correct. THE TRULY SUPERIOR UNDERSTANDING OF PHYSICS/PHYSICAL EXPERIENCE: E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED from F=ma. Carefully consider what is THE SUN. The Sun is E=mc2. The Sun is ALSO F=ma. This explains the PERPETUAL MOTION of the Sun, AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! ACCORDINGLY, GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) ALL of SPACE is NECESSARILY electromagnetic/gravitational (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This is, IN FACT, proven by F=ma AND E=mc2. (BALANCE AND completeness go hand in hand.) So, consider what is c (A POINT, A PHOTON). A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. The BALANCE of being AND EXPERIENCE is essential. Dreams balance being AND EXPERIENCE. In dreams, it is you AND other than you are IN BALANCE. Indeed, there is no outsmarting the GENIUS of dreams. Dream experience is/involves true/real QUANTUM GRAVITY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. (THE EYE IS THE BODY.) Dreams make thought MORE LIKE sensory experience in general, thereby improving upon memory AND UNDERSTANDING. INDEED, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. MOREOVER, it is ALSO a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. (THOUGHTS ARE INVISIBLE.) Dream experience is possible/potential AND actual IN BALANCE. BALANCE AND completeness go hand in hand. Dream experience is always that of what is the BALANCED MIDDLE DISTANCE in/of SPACE. GREAT. Dreams combine, BALANCE, and include opposites. By Frank DiMeglio
